This target is for the ATMega2564RFR2. This makes a great target for exploring IoT technologies, such as mesh networking protocols.

Programming

The ChipWhisperer's AVR programmer supports this target directly. No external programmer is required.

Schematic

See GIT Repo for PDF of schematic.

Board Layout

See GIT Repo for gerber files.

Radio Usage

Note NO ANTENNA is provided as the board is sold only as a sub-assembly and not designed to be used as a radio transmitter. Mounting a 2.4 GHz radio antenna (SMA, NOT reverse-polarity SMA) like Digi-Key P/N 1475-1014-ND could potentially require you to meet FCC/CE guidelines for RF emissions and is UNSUPPORTED USAGE.

Historical Note

The following is the original (-01) schematic. The -01 PCBs were never publicly released and used during development only. The following changes were made in -02:

  • MOSI/MISO was switched on Atmel device (requires PCB fix on -01, or PCB will not work)
  • TST connected to ground (requires PCB fix on -01, or PCB will not work)
  • CLKI pull down
  • GPIO3 is now optionally in control of 4066 instead of being hardwired
  • Serial resistors added on SCK/MISO/MOSI lines
