This ultra-compact development board delivers unmatched performance for space-constrained projects. The exact chipset of the board is the powerful Nordic nRF52840 (ARM® Cortex®-M4F) running at 64 MHz. It features advanced wireless connectivity supporting Bluetooth 5.4, BLE Mesh, and NFC. Its physical dimensions are a mere 21 x 17.8 mm, making it a true coin-sized powerhouse. Supported development environments include the Arduino IDE, MicroPython, and CircuitPython for seamless coding integration.
Engineered specifically for demanding IoT (Internet of Things) and Wearable applications, this development board strikes the perfect balance between high processing capability and ultra-low power consumption. Powered by the nRF52840 microcontroller, it is the premier choice for advanced makers, electronics engineers, and hobbyists diving into edge computing and TinyML applications.
Q: Does it support battery charging for portable projects?
A: Yes, the board features a built-in power management chip that allows you to charge standard 3.7V Lithium (LiPo) batteries directly via the USB Type-C port, with selectable 50mA or 100mA charging currents.
Q: Which programming languages can I use to develop on this?
A: It is highly versatile. It fully supports C/C++ via the Arduino IDE, as well as MicroPython / CircuitPython for rapid prototyping, catering to different developer preferences.
