This fully populated SMT board replaces the OEM logic board to allow you to take over control over the small drive unit. It is tested before shipping and programmed with the latest software at the time of order. An appropriate set of parameters is also programmed and parameters that do never require changing are hidden.

The on-board wifi module is no longer populated due to its poor connectivity. For setting parameters you will need an ESP based wifi board (see below) or you need to be comfortable with a command line tool.

The board has various analog and digital inputs but can also be fully controlled via CAN.

The kit includes matching connectors for the Tesla™ small drive unit (SDU) inverter. It requires soldering to fit the latter. This is not a beginners product, you need fundamental electronics knowledge to use it!

The community edition does NOT include personal support by me but you can get help at the forum and you can educate yourself in the adjacent wiki. If you do need personal support, you can buy engineering hours

As an optional extra you can order the MLX current sensors so you don't need to desolder them from the stock Tesla board. They just pull out of the gel.

You can now also choose how to communicate with the board

• Option 1: on board wifi module as always - advantage: already set up, disadvantage: poor connectivity when inverter closed
• Option 2: no on board wifi
• Option 3: a Wifi module that connects via CAN is provided at a discount. Advantage: good connectivity, disadvantage: needs to be connected to the CAN bus by you
