ISM Radio module with Cortex M0+

A Microchip ATA8510 radio transceiver in the 868 MHz band and a Microchip SAMD21 Cortex M0+ at 48 MHz are the two integrated circuits on the (Yarm) module mounted on the CM3-Home Full edition.

  • The ATA8510 is a ASK/FSK radio transceiver with high sensitivity (-122 dBm) and selectivity.
  • Tested range in open air of over 14 km at 750 bit/s and over 700m at 10kbit/s.
  • Capable to scan multiple radio channels with data link speed reaching 80 kbit/s.
  • Compatible with ISM 868MHz Energy Harvesting ACME Systems radio nodes.
  • MMCX antenna connector onboard with possibilities of external antenna or internal PCB antenna.
  • The SAMD21 is the same processor onboard the Arduino Zero: Cortex M0+ 32 bit.
  • 256 kbytes of FLASH and 32 kbytes of RAM. Completely available for user programming.
  • Compatible with Arduino sketches and bootloader.
  • 1 I2C/GPIO/serial port connected on one of the exposed Grove connectors.
  • 1 serial port connected to one of the Raspberry CM3 serial port.
