TYBT5 user manual 
Tuya Smart BLE Module 
1. Product Overview
TYBT5 is a Bluetooth (BLE) module designed by Hangzhou Tuya Information Technology 
Co., Ltd. The BLE Module consists of a highly integrated wireless Bluetooth chipTLSR826 7 and 
some extra electric circuits that have been programed with Bluetooth network protocol and plenty 
of software examples. TYBT5 include a 32-bit MCU, BLE，512K byte flash，16K byte SRAM 
and 9 multiplex IO pins. Users can customize their LED products by using these PWM signals.
