RF Performance and Antenna configuration Outdoor range 30m. Maximum Transmitting RF Power - 15 dBm. Receiving Sensitivity -78 dBm. Frequency ISM 2.404 - 2.475 GHz. Operation mode – Adaptive FHSS. Antenna – PCB “F” configuration.
Physical Dimensions L x W x H = 2.125 x 1.055 x 0.200 [in] SMT solder pads size (L x W) = 0.125 x 0.065 [in] Lead spacing (LS) = 0.100 [in]
Electrical Parameters Absolute maximum Supply Voltage Range 2.3 - 3.6 VDC Nominal Supply voltage – 3.3VDC Current Requirements - 200mA Operating Temperature Range - 0 to 70 °C / 32 to 158 °F
User Interface GPIO 6 GPIO connections are provided (with programmable / alternate functionality). These GPIO can take 0..3.3V voltage range and +/-6mA of current. Voltage exceeding these limits can result in damage to the module circuitry. Interrupt Capability is available on all pins.
PCB Material and layout considerations The PCB material for the base PCB should be FR4 glass epoxy.
