"textContent": "Challenger+ RP2350 NB-IoT is a Feather-compatible board pairing a Raspberry Pi RP2350 microcontroller and a certified NB-IoT cellular module with built-in GNSS, suitable for long-range, low-power connectivity. It looks to be a variant of the earlier Challenger+ RP2350 WiFi6/BLE5 board that replaces an ESP32-C6 WiFi 6, BLE, and 802.15.4 module with an STMicroelectronics ST87M01 NB-IoT and GNSS module. It still offers Challenger+ RP2350 NB-IoT specifications: Microcontroller – Raspberry Pi RP2350A MCU CPU Dual-core Arm Cortex-M33 processor @ 150MHz Dual-core 32-bit RISC-V processor @ 150MHz Up to two cores can be used at a given time Memory – 520KB internal RAM 8KB OTP Storage Package – QFN-60; 7×7 mm Memory – 8MB PSRAM Storage – 8MB SPI flash Cellular connectivity Module – STMicro ST87M01-1301 LTE Cat NB2 (NB-IoT), 3GPP Release 15 Worldwide regional bands coverage – B1, B3, B5, B8, B20, and B28 Single-tone / Multi-tone / Extended TBS and 2 [...]\n\nThe post Raspberry Pi RP2350 board offers NB-IoT cellular connectivity, GNSS, and Wi-Fi indoor location appeared first on CNX Software - Embedded Systems News.",
