BT2S Module Datasheet 1 PRODUCT OVERVIEW
1 Product Overview
BT2S is an embedded Bluetooth low energy (BLE) module that Tuya has developed.
It consists of a highly integrated Bluetooth chip (TLSR8250F512ET32) and several
peripheral components, with an embedded Bluetooth network protocol stack and
robust library functions. BT2S also contains a low-power 32-bit multipoint control
unit (MCU), BLE 5.0 component, 2.4 GHz radio component, 4 Mbits flash memory,
48 KB static random-access memory (SRAM).
1.1 Features
• Embedded low-power 32-bit MCU, which can also function as an application
processor - Dominant frequency: 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 to 3.6 V, the module
performance is normal.)
• Peripherals: 5×GPIOs, 1×UART, 1×ADC
• BLE RF features
– Compatible with BLE 5.0
– Up to 2 Mbit/s RF data rate
– TX power: +10 dBm
– RX sensitivity: –94 dBm at BLE 1 Mbit/s
– Embedded advanced encryption standard (AES) hardware encryption
– Working temperature: –20°C to +85°C
1.2 Applications
• Smart LED lights
• Smart households
• Smart low-power sensors
