Hardware Test V2.0

[besi]

To test

• Flash Micropython
• Run the motors
• Test the hall sensors
• Test I2C
• Internal Hall sensor 1
• Internal Hall sensor 2
• Neopixel
• Test Switches
• Temperature sensor
• DCF receiver (see Runtime error related to Timer(-1) dsiggi/micropython-dcf77#2)
• 12V circuitry trips the resettable fuse #8

Log

• Once the 5V trace is cut the USB-Port appears and the Chip can be flashed
• The 4MB module is used. The 8MB or 16MB would have been easier to set up with Micropython + Thonny since 8/16MB is the default for S3 chips.

Ideas for the next version

• R1 should be 0805 for easy hand soldering
• Add solder bridge parallel to R7
• Clearly denote the Hall sensor components since they're currently not assembled
• Angled switches that are on the front side of the pcb
• Uart header 90degree friendly on the edge of the pcb
