Waveshare BLE400 nRF51822 Bluetooth 4.0 Eval Board

Description

The Waveshare BLE400 evaluation board provides a complete development platform for the Nordic Semiconductor Semiconductor nRF51822 system-on-chip (SoC). This board integrates the core components required to design and test Bluetooth Low Energy 4.0 and other 2.4GHz wireless applications. Its architecture centers on the nRF51822’s ARM Cortex-M0 processor and integrated 2.4GHz RF transceiver, offering a balance of processing power and wireless connectivity in a low-power envelope.

Designed for system integrators and embedded developers, the board exposes all critical MCU pins through standard 2.00mm headers, facilitating easy connection to sensors, displays, and other peripherals via SPI, I2C, and UART interfaces. The onboard power regulation supports a wide input range from 2.0V to 3.6V, making it suitable for battery-powered wearable and IoT nodes. The integrated PCB antenna and programmable RF output power allow for tuning the wireless link budget for specific range requirements, typically up to 30 meters in open outdoor conditions.
