ILabs’ New RP2040 Connectivity Board Features u-blox SARA-R412M LTE (Cat M1/NB-IoT) and ESP32 Modules


ILabs’ RP2040 Connectivity Board is an RP2040-based development board with u-blox SARA-R412M for LTE (Cat M1/NB-IoT) and Espressif’s ESP32-C3FN4 for WiFi/BLE, designed for versatile IoT applications from remote monitoring to smart connected devices.

We’ve covered various connectivity boards like the SparkFun LTE Stick, and the Walter ESP32-S3, but the RP2040 Connectivity Board is unique as it combines an ESP32 and RP2040, offering the best of both worlds.

The board features Espressif’s ESP32-C3FN4 chip, providing advanced Wi-Fi and BLE. It’s powered by a RISC-V core with 4MB flash and 408KB SRAM and includes the ESP-AT interpreter for diverse network functionalities. It’s energy-efficient, with a 500mA battery charger, and has user-friendly reset and UF2 buttons, plus options for both onboard and external antennas.

It also includes the SARA-R412M module for LTE (Cat M1/NB-IoT), offering worldwide coverage and strong security features. This module connects to the RP2040 via a hardware serial port for fast data transfer and has an easy-to-install cellular antenna with a U.FL connector.

For network access, the board requires a nano SIM card. Users can choose their own SIM or opt for the 1NCE prepaid card, which provides 120 months of global connectivity for 150 SEK, including 500 MB of data and 250 SMS. The provided SIM card is meant for evaluation; for more features, users can directly contact 1NCE.
