- In general, follow the instructions in the Romi chassis assembly guide. Note that wheel encoders should be installed as shown in those instructions and will plug into the bottom board. - The interactive BOM is helpful while soldering components onto the board. - We recommend using headers between the boards so that disassembly is possible. Use female (socket) header on the bottom board and male (pin) headers on top board. Pin headers come with all of the breakout boards. - Use the top board to guide breakout board header soldering. Insert the pin headers into the appropriate positions on…
