ESP32-C3 SuperMini development board, 3.3V, ideal for IoT applications and portable devices, based on the Espressif ESP32-C3 chip, which offers high performance thanks to its 32-bit RISC-V processor, capable of fast operations and calculations.
The board includes support for WiFi 802.11 b/g/n and Bluetooth 5 (LE), providing excellent connectivity for wireless projects.
Its design is ultra-compact, weighing only 3 grams, with a single layer of surface-mount components (SMD), and the integrated antenna improves the wireless signal. The USB connection is Type-C (USB-C) and includes a voltage regulator to step it down from 5V via USB to 3.3V (the board's operating voltage).
It offers 11 digital pins that can be used as PWM and 4 analog pins compatible with ADC. It supports UART, I2C, and SPI interfaces, making it extremely versatile for various IoT applications.
In addition to low power consumption, the ESP32-C3 SuperMini includes advanced security features such as a hardware accelerator for AES-128/256 encryption, digital signatures, and Secure Boot, making it suitable for secure and efficient systems.

Usage:
The board can be powered with 5VDC through the USB-C connector or the 5V pin, but it is only compatible with 3.3V logic voltage, so do not use it with peripherals that exceed 3.3VDC.
Use Arduino IDE, ESP-IDF, or PlatformIO for development and programming the board. For Arduino IDE, add the following link in "Additional Boards":
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json
From the list of available boards in Tools->Board, select ESP32 Arduino->ESP32C3 Dev Module.
Bootloader mode: To upload firmware, hold down the BOOT button while powering the board. Alternatively, you can select the Enable option in the Tools->USB CDC on Boot menu, which allows code upload without entering the bootloader manually.
The GPIO8 LED indicates the board status. Use UART for debugging.
Very Important! When connecting, if the Boot button is not held down, the board enters a reset loop. Hold BOOT while connecting, select the port and board, then upload the code.
On first use, the board is in a reset loop because it uses native USB CDC, without an FTDI or CH340 chip. After uploading, once firmware is present on the board, this is no longer an issue. If the code does not upload, select the Enable option in the Tools->USB CDC on Boot menu.
The board uses a low-power SMD antenna, which limits signal strength. Consider another option with an external antenna if you want a greater WiFi range.
WiFi issue:
Some batches may have the antenna soldered too close to the processor and oscillator, which can lead to intermittent WiFi operation. This can be fixed by resoldering the antenna 1 mm farther away.

Dimensiunile miniaturale pot da impresia unui dispozitiv modest, dar... aparențele înșală, iar rezultatele utilizării ne vor depăși așteptările.
Exista mai multe variante de C3 ... din pacate in poza aferenta acestul articol ni se prezinta varianta cu semnal wifi bun, pentru ca are oscilatorul la distanta necesara fata de antena ceramica. Din pacate produsul livrat este cel fara spatiu intre ele iar calitatea semnalului wifi este foarte slaba. Se poate remedia, fie cu o antena lambda/4 facuta dintr-o sarma de cupru, fie cu alta antena.
Nu vă lăsați păcăliți de dimensiunile foarte mici! Acest dispozitiv știe foarte multe, este foarte ușor de utilizat și funcționează de la prima încercare, mai ales dacă setările sunt corecte și programul este bine scris. Cum s-ar zice... mic da'voinic!
O placa excelenta, nu am incercat inca Bluetooth, urmeaza dar pt cat de mica si la ce pret bun este, este minunata. Daca aveti probleme la upload, la mine a mers dupa ce mai dadeam cate un restart cu: tinut apasat Boot + scurt celalalt buton. Daca nu merge din prima incercati inca o data, dupa upload eu uneori (sau tot timpul) am fost nevoit sa decuplez de la usb si sa il contectez iar ca sa booteze si sa ia ce am programat.
Salut, am luat placa zilele astea. Am lipit foarte usor headerpini. Conectat la PC, adaugat libraria : https://espressif.github.io/arduino-esp32/package_esp32_index.json si in Arduino IDE folosesc : ESP32C3 Dev Module unde am pus si USB CDC On Boot: Enabled. Daca o conectati si tot se conecteaza si deconecteaza, tineti apasat abele butoane sa intre in boot, o reconectare apoi se rezolva. Momentan cu ce am testat eu nu vad sa fie probleme, isi merita banii si fiind asa mica o poti integra in multe proiecte DIY, eu intentionez sa fac o statie meteo.
