We have created an alternative bootloader to load apps stored on an SD card. A double tap of the reset button activates the bootloader. Use the 3/UP, 4/DN and 5/YES buttons to select the app.

Here is a short video demo:

We have ordered extra boards from Elecrow, so you are most welcome to place pre-orders for more ;)

PX-HER0 Board

One PX-HER0 board.



From the Crowd Supply Basics project.

A standalone debugging and programming mini probe by ST for STM32 microcontrollers. The JTAG/SWD interfaces can communicate with any target STM32 microcontroller. A virtual COM port interface allows the host PC to communicate with the target microcontroller through one UART. STDC14-to-STDC14 flat cable included. USB Type-A to Micro-B cable not included.



PICONOMIX was formed out of my desire to share knowledge, expertise and tools with our open community of engineers, scientists and makers.
