Get the same one as in the images above to be sure it mounts correctly.  I removed the black plastic standoff on the pins so that it sits flat on the PCB and gives enough headroom for the upper PCB and regulator.\n- You favourite blheli32 esc.  Make sure it has telemetry out and ideally a current sensor.\n- OLED 128*64.  There are 2 common version but the Vcc and GND pins are swapped.  This PCB has been designed to take both and you select which pin receives Vcc/GND by soldering the jumpers.\n- A 3V3 or 5V regulator.  Either can be used and solder the jumper to which ever voltage you have used.  This makes sure the ESP32 is powered correctly.\n- Optional loadcell for measuring thrust.\n\n\u003cimg src=\"/pcb/pcb.png\" width=\"600\"\u003e\n\n## If you make one I would love to see it.
