OpenSprinkler Forums Hardware Questions OS_3.2 connector purpose Reply To: OS_3.2 connector purpose



I am waiting for my board and parts to arrive to build a new OS 3.2, but I’m trying to wrap my head around how I will need to program this. I have a USB to serial module, so is it just a matter of soldering wires to the board and connecting them to the USB to TTL module (aka – No resistors/capacitors required), and then flashing the firmware from the arduino IDE? Or can I just follow the instructions for using node-mcu flasher found here:

connecting to the board using the usb to serial adapter? Thank you so much.

Edit: After studying the schematic, it looks like I can just use dupont connectors to connect to the JCON0 headers as well. Is that correct?
