Levetop new develop board available now. It is based on LT7686/LT7381 chip. The board is very flexiable and friendly for developer, it support standard 40pin or 50pin TFT panel , and also support 8 bit, 16 bit. SPI. I2C MCU interface. Developer can use the jumper to choose the interface they need and use their most familiar MCU to test our chip.
see below link to find more about Levetop develop board and demo kits.
