This module core processor ESP32-C3 is a Wi-Fi+ BLE combination of system-level chips (SoC), designed for various applications such as internet of things (IoT), mobile devices, wearable electronics, smart home, etc. You would then connect the signal pin from your Arduino to one of the signal pins on this module (for example, pin “HV1”), and then you would connect the desired signal pin on the module to the corresponding pin on this module (“LV1” if the higher voltage signal is connected to “HV1”).ĮSP-C3-32S is a Wi-Fi module developed by Ai-Thinker.
Then, you would connnect the “LV” pin on the module to the 3.3V power source that is supplying power to the module and connect the “GND” pin near the “LV” pin to the 3.3V power supply’s ground. For example, if you were connecting your Arduino (5V signals) to a module (3.3V signals), you would connect the “HV” pin on the module to the 5V supply pin on your Arduino and the “GND” pin near the “HV” pin to the “GND” pin on your Arduino. Also connect the lower voltage source to pin “LV” and its ground to pin “GND” near the “LV” pin. Connect the higher voltage source to pin “HV” and its ground to pin “GND” near the “HV” pin. This module requires you to supply it with power from both the higher voltage level and the lower voltage level.
