How to Pick an ESP32 SuperMini Board for Tiny Builds
Pick an ESP32 SuperMini when a full DevKit board will not fit your build. It comes in C3, C6, S3, and H2 versions, each with WiFi and Bluetooth. Prices run from $9.99 to $17.99 by version and expansion board. The C3 board suits small IoT jobs, while the S3 version suits camera and display work.
Quick facts
| Fact | Value |
|---|---|
| C3 SuperMini | $10.99, WiFi and Bluetooth |
| C6 SuperMini | $17.99, WiFi and Bluetooth |
| S3 SuperMini | $17.99, WiFi and Bluetooth |
| H2 SuperMini | $17.99, WiFi and Bluetooth |
| C3 expansion board | $9.99 |
| C6 and H2 expansion boards | $11.99 each |
Which SuperMini version fits your project?
The C3 SuperMini costs $10.99 and suits small IoT jobs. It gives WiFi and Bluetooth in the smallest price in this range.
The C6 SuperMini costs $17.99 and adds newer radio options. The S3 SuperMini costs $17.99 and suits camera and display work.
The H2 SuperMini costs $17.99 and suits low-power radio jobs. Pick the version that matches the radio your project needs.
What does the expansion board add?
The expansion board breaks the SuperMini pins out for bench wiring. It lets you prototype without soldering to the small board.
The C3 expansion board costs $9.99. The C6 and H2 expansion boards cost $11.99 each.
Fit the SuperMini on the expansion board first, then wire sensors to the broken-out pins. That keeps the small board safe from heat.
How does the SuperMini compare with the DevKit V1?
The DevKit V1 is a 30-pin WROOM-32 board with WiFi and Bluetooth. Its board versions cost $15.99 to $17.99.
The SuperMini costs $10.99 to $17.99 by version and fits tighter builds. Both boards work with the Arduino IDE.
Pick the DevKit V1 when you need 30 pins on the bench. Pick the SuperMini when the build must stay small.
When should you pick the ESP32-CAM instead?
Pick the ESP32-CAM when the project needs a camera. It costs $25.99 with an OV2640 camera module and 4MB of PSRAM.
The SuperMini has no camera connector in its listing. A camera job needs the ESP32-CAM or the ESP32-S3-CAM board.
The S3-CAM board alone costs $11.97 with 16MB of flash and 8MB of PSRAM. Add an OV2640 camera for $23.12 in total.
How do you use the SuperMini with the Arduino IDE?
Install the Arduino-ESP32 core and pick the matching SuperMini version. Espressif documents the core and its board options.
Load a blink sketch first to confirm the board and USB link. Then load your project sketch with the same board setting.
The NodeMCU ESP8266 board costs from $11.37 and gives a built-in OLED. It suits WiFi jobs that need a small screen.
How the options compare
| SuperMini option | Version | Price |
|---|---|---|
| C3 expansion board | C3 | $9.99 |
| C3 SuperMini | C3 | $10.99 |
| C6 expansion board | C6 | $11.99 |
| H2 expansion board | H2 | $11.99 |
| C6 SuperMini | C6 | $17.99 |
| S3 SuperMini | S3 | $17.99 |
| H2 SuperMini | H2 | $17.99 |
How do you start a SuperMini project?
