It is based on the nRF51822 IC (Nordic Semiconductor). The RE1 is installed on a host PCB as a solder-down module. It is programmable by the designer of the host PCB and has FCC modular approval for use in the U.S. when used with the software library for the Coriandolo Radio Protocol, provided by 64seconds. Features System:
System-on-Chip, nRF51822, (Nordic Semiconductor) AMR M0 processor and 2.4 GHz radio transceiver Technical specications: See the nRF51822 Product Specication On-board IC antenna Coriandolo Radio Protocol:
