About the BMW-K1200LT-ABS-Conversion PCB

BMW-K1200LT-ABS-Conversion is an open source STM32 PCB design by OstapFerensovych, published on GitHub under the MIT license. It is a 2-layer board measuring 61.4 × 49 mm, with 63 components from 43 distinct parts.

Its main chip is the STM32F042F4PX, from the STM32 family. Other key parts include the LM2904, LMC662AIM, SN65HVD230, AMS1117-3.3 and MC34063AD. By type, the board carries 22 resistors, 15 capacitors, 8 connectors, 7 diodes, 6 ICs and 4 transistors.

From the project

BMW K1200LT iABS to iABS gen 2 Conversion PCB

To retrofit BMW K1200LT motorcycle we used the ATE/Teves iABS-II module from 2010 R1200GS K25. iABS-II uses CAN bus to communicate with ZFE, DME modules in the original R1200GS schematic.

This project is developed to provide K1200LT necessary signals from ATE/Teves iABS-II CAN bus: - Speed signal for K1200LT dash - Brake and tail lights output - ABS warning LED output - General warning LED output
