Product Introduction
DT-ESP-C05 is a WiFi & BLE two-in-one module based on ESP32-C3FH4, which is resistant to high temperature and is convenient for lighting scenes. The module chip is ESP32-C3, the core chip has a built-in storage of 32Mbit, and has multiple certifications such as FCC/CE/SRRC. This is a more cost-effective module of the Espressif series Combo module.
Application Range
Smart home, industrial Internet of things, transparent market.
Technical specifications
A. Pin definition diagram
B. Module package drawing
C. Application schematic
D. How to program: GPIO9 can be programmed as long as the low level is grounded. After programming, cancel the grounding, otherwise it will not work.
Notices
1. The maximum instantaneous current of ESP32-C3 radio frequency can reach 400~500mA, so the minimum power supply requirement is 500mA. LDOs such as XC6206 and 7533 cannot be used;
2. ESP32-C3 has a slightly weaker anti-static ability. Pay attention to electrostatic protection in the dry season in winter;
3. Based on the 500mA power supply requirement, it is recommended that the wiring between the power supply and the ground is not less than 30mil. If the power line has vias, it is recommended to make 2~3 to prevent PCB production deviation;
4. For better RF performance, please refer to the module placement method in the manual. If the product has certification requirements, it is recommended that there is no parallel wiring near the PCB antenna, and the download interface should be reserved far from the antenna pad;
5. It is recommended to erase the module before downloading the program, otherwise there may be some failure to start;
6. If the module fails to start normally and keeps restarting, it is recommended to check the power supply line, including power supply material parameters, power trace width, vias on the power trace, diodes connected in series to the power supply, etc.;
