PICtail Daughter Cards

The CAN/LIN PICtail™ (Plus) Daughter Board (AC164130-2) can be used with either the Explorer 16 Board or the PIC18 Explorer Board. This daughter board is used to facilitate rapid implementation and evaluation of applications that use Controller Area Network (CAN) and Local Interconnect Network (LIN) interfaces. The PICtail Plus interface is used for connection to Explorer 16 Development Board for 16-bit and 32-bit MCUs. The PICtail interface is used for connection to the PIC18 Explorer for PIC18 8-bit microcontrollers.

An older version of this board that only supports connection to the Explorer 16 Development Board is still available. The ECAN/LIN PICtail™ Plus Daughter Board (AC164130) can only be used with the Explorer 16 Development Board for PIC24 16-bit microcontrollers and dsPIC33F Digital Signal Controllers.
This board supports the capacitive humidity sensor application note AN1016. It measures the capacitance of a relative humidity sensor plugged into the board. The on-board microcontroller sends the measured and calculated relative humidity (RH) to a PC for display.

The board can also measure small capacitors in different ranges of values using a dual slope integration method. The board can be modified, if desired, to achieve better measurement resolution.

The MCP2030 Bidirectional Communication Demo Kit demonstrates short range bidirectional communication applications using the features of the MCP2030. The demo kit consists of two units: (a) Base Station unit and (b) Transponder unit. The Base Station unit transmits a low frequency (LF) command looking for the transponder in the field. When the transponder unit detects the Base Station command, it responds with its ID and RSSI (Received Signal Strength Indicator) using UHF frequency (434 MHz). When the Base Station unit receives the response from the Transponder unit, it displays the received Transponder ID and RSSI data on the LCD. The features and concepts demonstrated by the demo kit can be used for low frequency (LF) sensing and various hands-free access control security applications. The bidirectional communication range is up to about 3 meters and mainly limited by the property of the LF frequency.
The MCP2515 PICtail™ Demo Board implements a simple CAN bus using two nodes. One node uses the MCP2515 Stand Alone CAN controller and the other node uses the MCP25020 CAN I/O Expander. Each node utilizes one input (push button) and one output (LED).

The boards demonstrate a simple, inexpensive implementation of a CAN bus. The MCP2515 node transmits its input (push button) information at regular intervals and request input (push button) information from the MCP25020 at regular intervals. An LED on each node reflects the state of the other node's push button.

The MCP3221 PICtail™ Demonstration Board is designed to demonstrate Microchip’s MCP3221 device. The demonstration uses DataView™ Windows® software for a graphical real time data analysis from the board through USB. This demo board can also be used for firmware development to the MCP3221 device using the PICkit™ 1 Flash Starter Kit.

The MCP3551 Delta-Sigma ADC Demo Board is designed to demonstrate Microchip Technology’s MCP3551 22-Bit Delta-Sigma Analog-to-Digital (ADC) Converter performance using DataView™ software installed on a PC. The demo board can be used with MPLAB® ICD2, PICkit™ 1 Flash Starter Kit, or PICkit™ 2 for developing demonstration/evaluation firmware. Optionally, a second installed MCP3551 can be used with and optional stimulus board (sold separately).

The board is designed to evaluate the MCP3551 with minimum Printed Circuit Board (PCB) noise. The PCB layout practices low-noise design to reduce the signal noise as much as possible in order to demonstrate the 22-Bit performance of the MCP3551.
The MCP39F501 Power Monitor PICtail™ Evaluation Board duals as a fully functional single-phase power monitor and development platform. This low-cost design does not use any transformers and requires few external components. The device calculates active power, reactive power, RMS current, RMS voltage, power factor, line frequency and other typical power quantities as defined in the MCP39F501 data sheet. The MCP39F501 Power Monitor Utility software is used to calibrate and monitor the system and can be used to create custom calibration setups. For some accuracy requirements only a single point calibration may be needed.
Use the MCP6S22 PGA PICtail™ Demo Board to evaluate and demonstrate Microchip Technology’s MCP6S21/2/6/8 Programmable and MCP6S91/2/3 Gain Amplifier (PGA) families.

Interface this board with Microchip’s PICkit™ 1 Flash Starter Kit to demonstrate firmware integration between the PIC MCU and PGA devices, while allowing you to modify and develop firmware for your specific requirements

The MCP6S22 PGA PICtail™ Demo Board can also be used in stand-alone mode, wherein the board uses a:

  • USB interface to communicate directly to a Personal Computer (PC)
  • Graphical User Interface (GUI) to display the PGA output voltage

The MCP6SX2 PGA Photodiode PICtail™ Demo Board features a PNZ334 photodiode, MCP6001U op amp, and MCP6S22 and MCP6S92 Programmable Gain Amplifiers (PGA).

The op amp converts the photodiode’s output current to voltage (transimpedance amplifier). Its output goes to one of the PGA’s inputs. The other PGA input is available for any other desired source. This opens the possibilities of processing other sensor signals, and of increasing the number of PIC® microcontroller I/O pin available for other purposes.

This board works with the PICkit™ 1 Flash Starter Kit (see DS40051) and the Signal Analysis PICtail™ Daughter Board (see DS51476). With these additional tools, a complete solution is achieved: PC software interface, PICmicro® microcontroller, firmware programmability, 10-bit ADC (on the microcontroller), and firmware (with re-locatable assembler code) for the microcontroller.

The MCP6SX2 PGA Thermistor PICtail Demo Board features the MCP6S22 and MCP6S92 Programmable Gain Amplifiers (PGA). These devices help:

  • Overcome the non-linear response of the on-board NTC thermistor
  • Provide multiplexing between two inputs; the other input can be any desired source. This opens the possibilities of temperature correcting another sensor, and of increasing the number of PIC® microcontroller I/O pins available for other purposes.

Two on-board variable resistors allow users to experiment with different designs on the bench. DIP switches on the board select certain resistors (in a binary weighted sequence) to add together, thereby emulating the series resistor in the voltage divider and the thermistor’s change in resistance over temperature.


A complete solution is achieved by interfacing this board to the PICkit™ 1 Flash Starter Kit (see DS40051) and the Signal Analysis PICtail™ Daughter Board (see DS51476). The solution provides:

  • PC software interface
  • PICmicro microcontroller
  • Firmware programmability
  • 10-bit ADC (on the microcontroller)
  • Firmware (with re-locatable assembler code) for the microcontroller.

When connecting to the two boards together, pay close attention to the orientation of the connector and pin alignment.

Board Configurations
A total of 7 jumper locations are available. As shipped from the factory, some of the jumper locations are bridged by circuit traces forming a default setup. To change this, the user will need to cut the traces and install pins and a block jumper. Afterward, the features can be enabled or disabled easily by installing or removing the jumper.
