Telink provides Bluetooth LE Multi Connection and Platform SDKs, both hosted on GitHub, and the Telink IoT Studio IDE for development. The latter works on Windows and Linux and supports firmware compilation, firmware download, and debugging.
Telink Semiconductor also designed two TL3228 development boards: The open-source hardware TL322X EV board used to verify the TL3228X/3828X series chips, and the AIOT-DK1 development platform for Telink modules, offering three standard MikroBUS sockets for Click expansion modules.
The company didn’t provide pricing information for the new chips, but the AIOT-DK1 development kit can be purchased for about $70 on Mouser. More details, including software and hardware documentation, can be found on the product page.
