1. Product Overview
TYBT3 is a Bluetooth (BLE) module designed by Hangzhou Tuya Information Technology 
Co., Ltd. The BLE Module consists of a highly integrated wireless Bluetooth chip TLSR8267 and 
some extra electric circuits that have been programed with Bluetooth network protocol and plenty 
of software examples.TYBT3 include a 32-bit CPU, BLE, 512K byte flash, 16k SRAM, and 9 
multiplex IO pins.

Note: P: Power supply pins; I/O: Digital input or output pins. 
SW pin is ONL Y used for burning firmware, Can NOT be used for other functions. 
There are 4.7 pull- up resistance internally for I2C pins, external pull-up resistances are not 
necessary. 
When WW pin is outputting PWM signal, It has opposite phase comparing the PWM signal 
from R/G/B/CW pin. 
If there’s any customization needed for PWM output, please contact our BD manager.
