1. Product Overview
TYBT1 is a Bluetooth (BLE) module desi gned by Hangzhou AiXiangJi Technology Co., Ltd,
which is designed for outputting LED control signals. The BLE Module consists of a highly
integrated wireless Bluetooth chip TLSR8266 and some extra electric circuits that have been
programed with Bluetooth network protocol and plenty of software examples. TYBT1 include a
32-bit CPU, BLE, 512K byte flash, 16k SRAM, 5-channel PWM, one I2C and one
UART interface.
Users can customize their LED products by using these PWM signals.
