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.

Frequently Asked Questions

What software development tools are compatible with this nRF51822 evaluation board?

The board is compatible with the Nordic Semiconductor nRF5 SDK and SoftDevice stacks for BLE development. You can program it using the Segger Embedded Studio, Keil MDK, or GCC ARM toolchains. For debugging and flashing, connect the board's SWD (Serial Wire Debug) pins to a Segger or compatible programmer. The onboard USB-to-UART jumper also allows for serial communication and bootloader updates via a standard USB cable.

How do I power the BLE400 board and what is its typical current consumption?

You can power the board via the 5V/3.3V input header or the onboard CR2032 battery holder, accepting a supply voltage between 2.0V and 3.6V. Typical operating current depends on the RF mode; during active BLE transmission at +4 dBm, expect currents in the range of 10-15mA. The nRF51822 supports deep sleep modes, reducing consumption to microamps for battery-efficient operation in sensor applications.

Can I use an external antenna with this board instead of the onboard PCB antenna?

The primary RF path is designed for the integrated PCB antenna. To use an external antenna, you would need to modify the board's RF layout, which requires expertise in RF design and impedance matching (50 ohms). For most evaluation and prototyping purposes, the provided PCB antenna is sufficient, offering a typical range of up to 30 meters in open space at 1 Mbps data rate.
