1 Product Overview
BT3L-A is an embedded Bluetooth Low Energy (BLE) module that Tuya has developed. It
consists of a highly integrated Bluetooth chip (TLSR8250F512AT32) and several
peripheral circuits, with an embedded Bluetooth network protocol stack and robust library
functions. BT3L-A also contains a low-power 32-bit multipoint control unit (MCU), BLE 5.0
or 2.4 GHz radio, 4 MB flash memory, 48 KB static random-access memory (SRAM), and
nine multiplexing I/O pins.
1.1 Features
