Finally, after several weeks delay, the new PCBs for the Mini Sumo Robots (see “Zumo Robot with WiFi and GPS”) arrived, and best of all: first tests are all running fine :-).
Beside of smaller bug and layout fixes, the new PCB features the following extensions:
- Additional user LED (now two) on the back
- Simpler and easier connection to the motor and quadrature encoders
- Bluetooth and nRF24L01+ connectors on the base board
The boards came with four boards on a bigger board:
With the exceptions of the Arduino Shield compatible headers and the reflectance sensor header, the boards have all the parts populated which is a big time saver in the course.
For the motors we are using now a micromatch cable:
Hopefully, everything comes together as planned ;-).
Happy PCBing :-)
