1 Product Introduction
1.1 General description
The TLSR8258 Dongle, which is based on Telink TLSR8258F512ET48 chip,
provides a Bluetooth LE wireless system.
The TLSR8258 Dongle integrates a power-balanced 32-bit
MCU, BLE /2.4GHz Radio, 64kB SRAM, 512kB internal Flash, 14bit ADC, 6-channel
PWM, flexible GPIO interfaces, and nearly all the peripherals needed for IoT (Internet
of Things) and HID (Human Interface Devices) application development
(e.g. Bluetooth Low Energy ).
The TLSR8258 Dongle supports standards and industrial alliance specifications
including Bluetooth Low Energy (up to Bluetooth 5), BLE Mesh, 6LoWPAN,
Thread, RF4CE, HomeKit, ANT and 2.4GHz proprietary standard.
