There are posts in the forum where we discussed the single supply variations for the RAK4630

RAK4631 - VDD_NRF (no) connection

Hello, I’m trying to include the RAK4630 within our custom boards and I have a doubt regarding the power supplies. According to the RAK4630’s datasheet, the supplies should follow these specifications: [image] I’m using the RAK4631 schematic as a reference but I can’t see what’s the connection of the VDD_NRF signal from the RAK4630. Below is the schematic, in green I’ve marked the parts related to the VDD_NRF, R4 and R8 are supposed to connect VDD_NRF to a supply but both are marked as NC (…

RAK4630 hardware design

Hi I am designing a small IoT PCB with RAK4630 and i see that in the schematic it says that L10 has to be removed to run the module of single 3.3V power supply. Does anyone know how to do this, as I think L10 is inside the module shield can? Has anyone used this module with a single 3.3V power supply? If yes, what sort of sleep current did you achieve? I find the sleep current is too high and i doubt if it is down to this, so any help is much appreciated. [image]

RAK4631 without baseboard

Hi, I have a RAK4631 Arduino version LoRa end node with me, due to some space constrains and low power application I am forced not to use any baseboard. I need your guidance and support to connect RAK4631 to TTL module so that I can program or debug my module and how do I power up my module do you have any documentation supporting my query? Thank You, Divya M
