 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I used the core of Peter's circuit design (Picomite HDMI v1.3, thanks @Peter!) for a new robot control board. Converted the EasyEDA files to KiCad and added circuitry for motor, LCD etc. control. PCBway did not want to produce it, because the pads of the RP2350 footprint were too close (?) - JLCPCB had no problem with that and the board works nicely  Interesting experience ... |

Incidently, I recently got my hands on a robot kit (Miika). It's a bit too expensive to by it from the original company, but it is well made and the mechanics is nice - two motors turn and walk the robot in any direction. The idea is that you train an AI on your cellphone such that you can make gestures to your phone to steer the robot. I thought that is is a bit silly and that the nice kit needs MMBasic ... The original board (pictures below, right) has an ESP32, and LED matrix and a buzzer, as well as connectors for two motors. No options for adding sensors and such. My redesigned board (left) allows to connect two motors, I2C devices (sensors), and a Bluetooth breakout. I also added a 240x240 TFT display, a few LEDs and a USB connector. All controlled by an RP2350 (using Peter's core design). As soon as I tested all components, I'll continue building the robot and then the software ... Front:  Back:  Here is the new board sticking in one half of the robot:  |
