E105-BS21-TB SparkLink Low Energy Module Development Board
[Power supply interface]：USB
[Communication interface]：UART
[Product size]：62.74 * 25.4mm
[Introduction]：E105-BS21-TB is an entry-level development board equipped with the SLE1.0 protocol SparkLink module E105-BS21. The SparkLink module development board has complete SLE1.0 Star Flash functions, and most of the pins of the Star Flash module on the board have been led out to the pin headers on both sides. Developers can easily connect a variety of peripheral devices through jumpers according to actual needs, and the development board can also be plugged into a breadboard for use.
| serial number | Main firmware | Description |
| 1 | E105-BS21 | E105-BS21 and E105-BS21X are serial to SLE (SparkLink Low Energy) starlight modules based on the StarLight protocol version 1.0. They have small size, low power consumption, long transmission distance, fast transmission speed, strong anti-interference ability, and low latency. It has time and other characteristics, operates in the 2.4GHz frequency band, and the maximum RF transmit power is 6dBm. |
