Dear sundberg84, thanks to your really nice and easy mysensors PCB. I ordered ten of them via SEEED and they were delivered today (REV.10). Unfortunally I found some serious bugs in the PCB design regarding the SPI Flash: First pin 6 (SPI SCK) of the flash chip is not connected at all - should be digital IO pin 13 of the Arduino pro mini. Second mistake: the filter capacitor of the flash chip is not between VCC and GND. Third mistake: pin 3 and pin 7 should be connected to VCC and not to the filter capacitor. I changed that on my arrived boards and the flash chip is now working perfectly. Kind regards, JPM
