💬 NRF2RFM69

[shabba]

I have converted all my old (3.3v) NRF24 sensors to RFM69 using these. Work great.

Looks Nice!!! Excuse me for my ignorance.

• What's c1 marked on the board?
• Would I be able to use this with jModule?

[tbowmo]

@SubodhChettri

C1 can be used to add a capacitor to the board.

@tbowmo Thanks

[gohan]

Just addition info: I found THIS that could an option for those who have spare RFM69CW modules or if they want to add some storage

[bilbolodz]

@tbowmo How about PCBs.io? Any chance for direct link? I've trying to upload it but got an error about "Gerber normalization for Layer: Drill Holes". I'm a quite newbie for designing/uploading files for PCB factories so sorry for maybe stupid question.

[gohan]

I ordered 10 from Seeed Studio and I had no problems; I am waiting for delivery.

[bilbolodz]

@gohan Seeed Studio ask 11.16 for delivery :-(

[bilbolodz]

I've uploaded (I hope all will be fine with PCB) on PCBs.io: https://pcbs.io/share/zZAMk
3.10 USD for 4 pieces free shipment

[gohan]

I had other pcb in order so shipping cost was not that bad, in addition 10 pcbs are 4.90$

[tbowmo]

@bilbolodz

There is also a link to dirtypcbs somewhere in this thread, where you can order pcb's.

@tbowmo i have some left over. If you are interested just shoot me a pm
Thanks

@jeti

Thanks, but I still have a couple left in my parts bin :)

[gohan]

Is it just me or there are some pins that are not exactly the same order as a normal 8 pins nrf24?

[tbowmo]

@gohan what do you mean?

[gohan]

Like CE pin is actually connected to the CSN pin on the 2x4 pin side

[tbowmo]

@gohan

On NRF24 CSN is equivalent of CE signal on the SPI bus. While CE is a global on/off switch for the TX/RX on the NRF (Check page 11 in the nrf24 datasheet

On RFM69 CE is actually called NSS (pin 15). Datasheet are here

I don't have the schematics of this project at hand right now, as someone has forgotten to add a pdf of it to the repository ;)

[gohan]

I haven't mapped all the pins because yesterday I was a little tired, maybe tonight I'll check, but the fact is that I can't initialize the radio while the nrf24 works. 😕
