CRAPOLA! NEVERMIND! I was wrong and thinking of the bridged version (the one I use here. . .) SORRY, MY BAD. Each socket on the handyboard will control 1 (ONE, UNO, UN. . .)

With the non-bridged board, each socket will control 2 boards. So for board 1, you'll connect to pins 1 and 2 in the socket, and for board 2 connect to pins 9 and 10. The other pins you can do as you please (for the brake, current sense, and thermal (...) (26 years ago, 9-Apr-98, to lugnet.robotics.handyboard)
