Hi, I’m trying to create my pcb and I’m using Seeed Studio NRF52840 as inspiration for board shematic design. But I’m stuck at few parts, so can somebody tell me where I should connect this circled connections. Also can somebody suggest me small pMOS and small voltage regulator.
Hi there,
I would say at the red Arrow…
it’s called out in the pins XLS on WiKi
B5 DEC4 Power 1.3 V regulator supply decoupling Must be connected to DEC6 (pin E24)
I don’t see the CE, but pretty sure the VIN is a Tag only , it’s on the C3 also.
Send Seeed tech support an e-mail and ask also.
