The Lighting Communications Development Platform provides a universal lighting development platform for the creation of communications enabled lighting applications. The platform consists of a main board and various communications interface adapters to support in the development of DALI, DMX512A, as well as future protocols.
The Serial SuperFlash® Kit 2 allows evaluation of Microchip's Serial Flash Devices which are made using the SST SuperFlash® technology. The Serial SuperFlash Kit 2 contains three Serial Flash Daughter Boards. The Serial Flash Daughter Board is an evaluation board designed to interface with the mikroBUS™ connector on the Explorer 16/32 Development Board (DM240001-2). It can also interface with the PICtail™ Plus connector located on the Explorer 16 Development Board (DM240001).
The CL88020 120VAC office LED Driver Evaluation Board is a complete solution consisting of an LED Driver (ADM00766) and an LED Load Board (ADM00767) powered directly from the 120VAC line and based on Microchip Technology's CL88020 Sequential Linear Driver.
Microchip’s Digital High Intensity Discharge (HID) Ballast Reference Design showcases the benefits digital control can bring to an HID ballast. HID ballasts must go through the complicated process of igniting the HID bulb and then transitioning it into steady state operation. Typically HID ballasts require a large set of analog controllers to properly control the HID lamp. However, using digital control techniques a single Microchip dsPIC device is able to control the entire HID ballast, reducing the ballast’s components and costs. Microchip’s Digital HID Ballast Reference Design is designed to interface to a standard automotive HID lamp. The reference design uses 9-16VDC and outputs 35W of steady state power and reaches an efficiency of over 85%. To handle changes in the input voltage and current, the reference design implements under voltage, over voltage, and over current protection. Using the reference design, a standard HID automotive bulb is able to reach steady state light output in under 150 seconds. Finally, since size is important in most ballast applications, the reference design uses planar magnetic to reach a small size of 9mm x 60mm x 80mm, commonly referred to as a “slim” ballast form factor. All documentation, schematics, and software can be found below. This reference design is royalty free when used in accordance with the licensing agreement.

The HV9805 120VAC Off-Line LED Driver Evaluation Board is used to evaluate and demonstrate Microchip Technology Inc.'s HV9805 device in the following topology:
•215-265V output Boost Converter application followed by a LED-side linear current regulator, supplied from the mains 120VAC, to drive a 70-90 LED string.
The HV9805 120VAC Off-Line LED Driver Evaluation Board was developed to help engineers reduce the product design cycle time.
The HV9805 230VAC Off-Line LED Driver Evaluation Board is used to evaluate and demonstrate Microchip Technology Inc.'s HV9805 device in the following topology:
•420-430V output Boost Converter application followed by a LED-side linear current regulator, supplied from the mains 230VAC, to drive a 130-150 LED string.
The HV9805 230VAC Off-Line LED Driver Evaluation Board was developed to help engineers reduce the product design cycle time.
The HV9805 230VAC SEPIC Evaluation Board is used to evaluate and demonstrate Microchip Technology Inc.'s HV9805 device in the following topology:
The HV9805 230VAC SEPIC Evaluation Board is suited for driving a 125V/100 mA LED load from a 230VAC source.
The Single-ended primary-inductor converter (SEPIC) configuration extends the application range of the HV9805 driver Integrated Circuit (IC) to lower LED load voltages than otherwise possible with the boost configuration. Many features of the boost configuration are retained, such as a true direct current drive of the LED load, high input power factor, high efficiency and simple magnetics.
The HV98100 120VAC Off-Line LED Driver Evaluation Board is designed to demonstrate the performance of Microchip Technology Inc's HV98100 LED Driver IC. The evaluation board drives a 120V LED string at 120mA from a 120VAC input voltage with high input Power Factor and low Total Harmonic Distortion.

The HV98101 230VAC Off-Line LED Driver Evaluation Board is designed to demonstrate the performance of Microchip Technology Inc's HV98101 LED Driver IC. The evaluation board drives a 100V LED string at 100mA from a 230VAC input voltage with high input Power Factor and low Total Harmonic Distortion.
The MCP1252 Charge Pump Backlight LED Demo Board demonstrates the use of a Charge Pump device in an LED application. The board also serves as a platform to evaluate the MCP1252 device in general. The MCP1252-ADJ is an excellent choice for biasing the back lighting or driving other LED applications. Light intensity is controlled uniformly through the use of ballast resistors. The peak intensity is set by the feedback to the the MCP1252-ADJ. Dimming is accomplished by pulse-width modulating the shutdown pin of the device.

The board also feature a PIC10F206 microcontroller in a SOT23 package, which is used to provide an enable signal to the MCP1252. The PICmicro also accepts a push-button input that allows the user to adjust the white LEDs to five different light intensities, in addition to placing the system in a standby mode that consumes less than 1 uA of current (typical).

The MCP1630 Boost Mode LED Driver Demo Board is a step-up, switch-mode, dc-dc converter used for power LED applications. The demo board provides a 350 mA or 700 mA constant current source with a jumper selection. The input operating voltage range is 9VDC – 16VDC and the board can supply up to 30W to a string of power LEDs.

The MCP1631HV Digitally Controlled Programmable Current Source Reference Design is used to drive and dim one or more power LEDs in a series or parallel topology (depending on the LED’s capability). The reference design may also be used to charge one to four cell NiMH/NiCd or one to two cell Li-Ion battery packs. The board uses the MCP1631HV high-speed analog PWM controller and PIC16F616 microcontroller to generate the proper dimming ratio for LEDs or charge algorithm for NiMH, NiCd and Li-Ion batteries. The boards is used to evaluate Microchip’s MCP1631HV in a SEPIC power converter application.

The RN4677 PICtail/PICtail Plus is a Bluetooth Dual Mode development board using the Microchip RN4677 Bluetooth Dual Mode module. The RN4677 module is a Dual mode Bluetooth module that complies with Bluetooth Core Specification 4.0. The RN4677 uses a simple ASCII command interface over the UART. The board enables evaluation of the RN4677 and development of Bluetooth low Energy applications in two different ways:

1) Out of the box:  When plugged into the USB port of a PC, the board will enumerate as a Communication Device Class (CDC) Serial device.  Through a terminal program, users can configure and control the module and transfer data using the easy to use provided command set.

2) As a PICtail/PICtail Plus, the board interfaces to one of hundreds of available PIC Microcontrollers through this  standard Microchip interface.  The PICtail bridges the host MCU UART to the RN4677's UART interface for data transfer or configuration using the straight-forward, easy-to-use ASCII style command set.
