PS: Based off my rants about the lack of cheap hobbyiest nRF52 boards; here's a PCB I adopted. Features a RESET button and SWD pinout; and LIPO battery charging (for those low power applications!! Why else would you want an integrated soulution?! :smiley: ). It houses the E73-2G4M08S1E modules sold in Taoboa for $2.50. It's open licensed but with interest I could accumulate locally for posting...
