64seconds Coriandolo Radio RE1 Module Userâs Manual RE1 Specification for the Designer Product Summary Features Pinout Package Outline Recommended Footprint Regulatory Notices RE1 Specification for the Designer Product Summary The RE1 is a hybrid, frequency hopping / spread spectrum radio module that operates in the unlicensed 2.4 GHz frequency band. 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 specifications: See the nRF51822 Product Specification On-board IC antenna Coriandolo Radio Protocol: 5 frequency channels, hopping sequence: 2472, 2402, 2422, 2446, and 2480 MHz Over-the-air data rate of 1 Mbps Coriandolo Radio Protocol for sending and receiving data Transmit power of -30 to +4 dBm Fixed modulation: GFSK, 500 kHz 6 dB bandwidth, 1 MHz 20 dB bandwidth Modular approval under FCC rules Part 15.247 when used with the Coriandolo Radio software library ARM M0 32-bit Processor: Fully programmable by the host designer 16.00 MHz and 32.768 kHz quartz crystal oscillators Peripherals available in the nRF51822 IC 16 KB RAM 128 KB flash Transparent Interface: 16 general purpose input/output ports, with pin selectable special functions Analog interface: ADC, voltage reference, and low-power comparator Serial interface: SPI, I2C, and UART Serial Wire Debugging (SWD) 2-wire interface for programming Pinout Pin nRF51822 Name Type Description GND Ground GND Ground VCC Power 1.8 - 3.6 VDC P0.00 / AREF0 GPIO Alternate function: Voltage reference 0 P0.01 / AIN2 GPIO Alternate function: Analog input 2 P0.02 / AIN3 GPIO Alternate function: Analog input 3 P0.03 / AIN4 GPIO Alternate function: Analog input 4 P0.04 / AIN5 GPIO Alternate function: Analog input 5 P0.05 / AIN6 GPIO Alternate function: Analog input 6 / voltage reference 1 10 P0.06 / AIN7 GPIO Alternate function: Analog input 2 11 P0.07 GPIO 12 P0.08 GPIO 13 P0.09 GPIO 14 P0.10 GPIO 15 P0.11 GPIO 16 P0.12 GPIO 17 P0.13 GPIO 18 P0.14 GPIO 19 P0.15 GPIO 20 SWDIO / nRESET SWD Serial Wire Debug I/O: reset line 21 SWDCLK SWD Serial Wire Debug Clock 22 GND Ground 23 GND Ground 24 GND Ground 25 GND Ground 26 GND Ground Package Outline The figure below shows an outline of the RE1 module, with a view of the component placements and antenna trace. Footpri Recommended Footprint The figure below shows the recommended footprint - or land pattern - on the host PCB, together with keep-out areas for ground plane, traces, and vias. Regulatory Notices This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications to the RE1 module hardware or to the Coriandolo Radio Protocol software that are not expressly approved in writing by 64seconds could void the userâs authority to operate the equipment.
