AITRIP 1PCS Type-C ESP32 ESP-WROOM-32 Development Board WiFi + Bluetooth CP2102 Dual Core 2.4Ghz Microcontroller Compatible with Arduino (ESP32 30P, Type-C)

Let me tell you about this **AItrip 1PCS Type, C ESP32 ESP, WROOM, 32 Development Board, it's honestly amazing. I’ve become quite the tech enthusiast lately, and this little device has seriously made my projects so much easier and more enjoyable. What I love the most is the WiFi and Bluetooth capability, which means I can set up various projects without any hassle. The dual, core microcontroller really enhances the performance, making it perfect for everything from simple tasks to more complex applications. The best part is that it’s durable enough to handle the usual wear and tear in our busy household, which is always a plus for me. At the end of the day, I'm really happy with this **AItrip 1PCS Type, C ESP32 ESP, WROOM, 32 Development Board.

Great ESP32 device and though there's no documentation. Anyone who know what these are don't need any instructions. Was able to flash a custom firmware to use on a small build and everything works. All 3 module accepted the flash with no issues and was very easy to use and flash. So far it's working and I'm able to stream my audio from the phone to another Bluetooth device. Great little module for the money and there are endless features you can do with these ESP32 modules.

I bought this ESP32 for a digital seismograph I'm working on. The functionality of this thing is amazing. I was able to hook it up to my ADC without any problems, alongside a micro SD card reader. Not only that but I was able to run a local webserver in which I could see my graph. It's pretty fast too, I haven't had any delays with processing data at all. It's small size and very little required power source makes this great too. It's versatility will allow you to pretty much use any type of electrical component with it, and I have not runed into any compatibility issues so far with any of my parts. Only thing I would consider a con would be that you'll have to learn C++ in order to program it. Overall, I would recommend this board for any type of low power project you may need.

Arduino sketch to id the chip #include "WiFi.h" #include "esp_system.h" void setup() { Serial.begin(115200); delay(1000); Serial.println(); Serial.println("=== ESP32 Chip Info ==="); // Chip ID is derived from the factory-programmed MAC address uint64_t chipId = ESP.getEfuseMac(); Serial.printf("Chip ID (from eFuse MAC): %04X%08X\n", (uint16_t)(chipId >> 32), (uint32_t)chipId); Serial.print("Chip model: "); Serial.println(ESP.getChipModel()); Serial.print("Chip revision: "); Serial.println(ESP.getChipRevision()); Serial.print("Number of cores: "); Serial.println(ESP.getChipCores()); Serial.print("CPU frequency: "); Serial.print(ESP.getCpuFreqMHz()); Serial.println(" MHz"); Serial.print("Flash size: "); Serial.print(ESP.getFlashChipSize() / (1024 * 1024)); Serial.println(" MB"); Serial.print("Free heap: "); Serial.print(ESP.getFreeHeap()); Serial.println(" bytes"); Serial.print("MAC address: "); Serial.println(WiFi.macAddress()); Serial.println("========================"); } void loop() { // Nothing to do here - info printed once at boot } result of script is is === ESP32 Chip Info === Chip ID (from eFuse MAC): 0468E7F57630 Chip model: ESP32-D0WD-V3 Chip revision: 301 Number of cores: 2 CPU frequency: 240 MHz Flash size: 4 MB Free heap: 325860 bytes

I bought a set to use as a Bluetooth proxy with Home Assistant and things that were unstable and laggy are now basically instant and perfect. Love it and now I'm trying to figure out how to use the others. Also, these are quite small and super easy to power. Basically, super great value. Oh, if you have issues use ESPHome to flash projects onto your ESP32? Make sure to download the drivers. That threw me for a loop for a bit.

Works great!

Only two of the three modules worked. One is unable to communicate with its Flash chip. Of course it was the first one I tried, so I spent a while checking everything else... The ESP modules on these boards are quite scuffed up and I suspect they're actually removed from some other equipment. The other two seem to work fine so far. Good thing they're cheap.

Good pins and wifi work
