                  Classification Parameter Value
                  Wireless parameter Working frequency WH-NB73-B5: Uplink: 824~849MHz
                  Downstream: 869~894MHz
                  WH-NB73-B8: Uplink: 880-915MHz
                  Downstream: 925~960MHz
                  Transmit power Transmitting power: 23dBm~-40dBm
                  Receiving sensitivity -129dBm
                  Hardware paramete Data interface UART: 4800bps, 9600bps, 57600bps, 115200bps
                  Operating Voltage 3.1V~4.2V, recommended 3.8V
                  Working current Maximum emission current in Active mode is 268mA@3V8
                  Receive current 64.5mA@3V8 in Active mode
                  Idle current 4.3mA@3V8
                  PSM current 5μA@3V8 (10μA@3V8 in simple transparent transmission mode)
                  Operating temperature -30°C ~ +85°C
                  Extended temperature: -40 ° C ~ +85 ° C
                  In the extended temperature, RF performance such as module transmit power may decrease, exceeding the 3GPP conformance requirements.
                  Storage temperature -40°C ~ +85°C
                  Working humidity 5%~95% RH (no condensation)
                  Storage humidity 5%~95% RH (no condensation)
                  Size Size: 27.99mm x24.50mm x 2.80mm
                  Package interface SMT surface sticker

                  Package includes:

                  1 x Module
