1 Product Overview
BT2L-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. BT2L-A also contains a low-
power 32-bit microcontroller unit (MCU), BLE 5.0 or 2.4 GHz radio, 4 MB flash memory, 48 KB static
random-access memory (SRAM), and five multiplexing I/O pins.
1.1 Features
 Embedded low-power 32-bit MCU, which can also function as an application processor
- Clock rate: 48 MHz
 Working voltage: 1.8 V to 3.6 V (Under 1.8 V to 2.7 V, the module can start but the RF
performance is not guaranteed. Under 2.8 V and 3.6 V, the module performance is normal.)
 Peripherals: five pulse width modulation (PWM) pins
 BLE RF features
- Compatible with BLE 5.0
- Up to 1 Mbit/s RF data rate
- TX power: +10 dBm
- RX sensitivity: –94.5 dBm at BLE 1 Mbit/s
- Embedded Advanced Encryption Standard (AES) hardware encryption
- Onboard PCB antenna
- Working temperature: –20°C to +105°C
1.2 Application Scenarios
 Smart LED lights
 Smart households
 Smart low-power sensors
