Clipper lets you receive and transmit data over 4G LTE cellular networks—perfect for remote or mobile projects where WiFi isn't available. Ideal for festival installations, garden sheds, beehive sensors, canal boats, or any project with a remote or transient location. Features a SP/CE connector for easy cable connection to compatible microcontrollers, plus an SMA connector for antenna attachment. Transmitting sensor readings typically uses minimal data, so pay-as-you-go plans work well. Key Features 4G LTE Connectivity – SIMCom A7683E module SP/CE Connector – 8-pin JST-SH for easy cable connection SMA Antenna Port – Attach external antenna SIM Card Slot – Use any compatible SIM No Soldering Required – Connect via SP/CE cable AT Command Control – Standard SIMCom AT commands Specifications Module: SIMCom A7683E Frequency Bands: LTE-FDD B1/B3/B5/B7/B8/B20/B28 Dimensions: 35mm × 29mm × 5mm (antenna connector 11mm tall) Power Input (VDD): 3.7V–6.0V IO Voltage (VDDIO): 3.0V–3.6V Current (idle): 17mA Current (sleep): 0.12–1.63mA Current (peak TX): 700mA (brief, capacitor-smoothed) Starter Kit Contains 1× Clipper 4G LTE Breakout 1× SP/CE cable 1× Antenna (108mm) Compatibility Raspberry Pi Pico / RP2040 / RP2350 Raspberry Pi computers Any SP/CE compatible microcontroller Regional Note: Supports bands B1/B3/B5/B7/B8/B20/B28. Check your local carrier's 4G LTE bands before ordering—coverage may be limited in North America.
