    I need a custom PCB that uses: - HDC1080 - nRF52810 - 2450AT42A100 antenna - CR2450 battery (3v) - With holder which will be THT, so you have the components on one side and the battery on the back. I’m going to be using a TC2050-IDC-430 + SEGGER J-Link to flash the device - so will need some pogo pins which can be used to flash the device.
