General

This module was developed in need of a affordable programmer for our busware gadgets CPM-BS, CSM, CUN.

It features a 8-bit bidirectional low voltage translator down to 1.0 Volt. Busses as SPI, I2C and UART are available on the 2x5 100mil pinheader. The module can optionally power the target with 5V. This will make the creation of user-specific-adapters (JTAG, RS485, 1wire etc.) easy.

Proper covers are also available ;)
