Makerdiary nRF9151 Connect Kit Brings IoT Dev Board with LTE-M, DECT NR+, GNSS to Developers

Makerdiary has recently introduced the nRF9151 Connect Kit, a rapid prototyping kit designed for Cellular IoT applications, featuring LTE-M/NB-IoT, DECT NR+, and GNSS connectivity. Built around the nRF9151 SiP with a 64 MHz Arm Cortex-M33, 1 MB Flash, and 256 KB RAM, it supports secure processing with Arm TrustZone and CryptoCell. The board includes an onboard nRF52820 SoC-based Interface MCU for CMSIS-DAP debugging, a USB-UART bridge, and an interface shell for setup.

It offers a USB-C port, nano-SIM/eSIM support, a battery socket, and U.FL cabled antennas in an easy-to-use dual-row 40-pin form factor. The power management system integrates a BQ25180 I2C battery charger and TPS63901 buck-boost converter, ensuring ultra-low quiescent current with 1.8V/3.3V configurable I/O supply.

Makerdiary previously released other interesting kits, including the iMX RT1011 Nano kit, the Pitaya Go IoT Development Board, and many more. Compared to those, the nRF9151 Connect Kit is more innovative because of Nordic’s nRF9151 SoC.
