[Bluetooth 4.2 & CH571F RISC-V Chip] Compatible with TI CC2540. This module supports Bluetooth 4.2 Low Energy (BLE). Offers faster data rates (MTU up to 256 Bytes) and lower power consumption (only 6mA at 0dBm) compared to older Bluetooth 4.0 modules, ensuring a more stable and efficient connection.
[Unique Wireless Programming for Arduino] Stand out with the ability to upload sketches to your Arduino Uno wirelessly! The NL-16 supports wireless programming, eliminating the need for USB cables during project debugging—a game-changer for robotics and enclosed DIY projects.
[Long-Range Transmission] Engineered for superior RF performance, It provides reliable long-distance data transmission that most standard BLE modules cannot match.
[Dual Configuration Modes] Flexible and easy to use, it supports both standard UART Serial AT commands and Wireless Bluetooth configuration. You can effortlessly modify the device name, service UUID, transmit power, and pairing password to suit your specific application needs.
[Professional Grade Design] Features a wide operating frequency (2.4GHz) and high receiver sensitivity (-96dBm). Designed as a "Single-Mode BLE" (Bluetooth Smart) device, it is optimized for modern mobile integration (iOS 7.0+ / Android 4.3+) while maintaining a compact footprint for embedded systems.
