I am looking at this IC PCF5001T
pdf.datasheetcatalog.com/datasheet/philips/PCF5001T.pdf
chosen based mostly on availability, I think the DI(pin 17) will work with the digital out pin from the HopeRF RFM23BPW.
The POCSAG controller has a read cycle pin which should be able to trigger wake/rx on the hopeRF IC so we might be able to save some W/h.
Thoughts?
I would LOVE to find a cheap breakout SM PCB for SOT136 packages so I don't have to hand micro-solder with magnet wire this PCF5001 and glue it down onto a perfboard.
I am assuming the Pinephone add-on is going to be a 433mhz?? It looks like I can tune the hoperf module to commercial and amateur radio 400-500 mhz area paging freqs though I hope it will work with the band passes on the board though we can bypass and change if required.
