Introduction to BLE Module--TYBLC3
Introduction to BLE Module–TYLC3
TYLC3 is a Bluetooth (BLE) module designed by HangZhou Tuya Technology Corporation, 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. TYLC3 include a 32- bit CPU, BLE/2.4G radio, 512K byte flash, 16k SRAM and 4-channel PWM.
Users can customize their LED products by using these PWM signals. Figure 1 shows the block diagram of the TYLC3.

6.2 Production Guide
The storage for the delivered module should meet the following condition:
- The anti-moisture bag should be kept in the environment with temperature < 30℃ and humidity < 85% RH.
- The expiration date is 6 months since the dry packaging products was sealed.
- All the operators should wear electrostatic ring in the whole process of production.
- While operating, water and dirt should not have any contact with the modules.
