This item exceeded my expectations, it had the exact amount of flash and PSRAM available, and as an added bonus, it had octal SPI for the PSRAM. I flashed it with no problem using the example code in esp-idf, and it had the following output: ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x1 (POWERON),boot:0x8 (SPI_FAST_FLASH_BOOT) SPIWP:0xee mode:DIO, clock div:1 load:0x3fce2820,len:0x14f0 load:0x403c8700,len:0xd24 --- 0x403c8700: _stext at ??:? load:0x403cb700,len:0x2ef0 entry 0x403c8924 --- 0x403c8924: call_start_cpu0 at C:/Users/weiqi/Downloads/esp-idf-v5.5.3/components/bootloader/subproject/main/bootloader_start.c:27 I (24) boot: ESP-IDF v5.5.3-dirty 2nd stage bootloader I (25) boot: compile time Mar 18 2026 18:44:50 I (25) boot: Multicore bootloader I (25) boot: chip revision: v0.2 I (28) boot: efuse block revision: v1.4 I (32) boot.esp32s3: Boot SPI Speed : 80MHz I (36) boot.esp32s3: SPI Mode : DIO I (39) boot.esp32s3: SPI Flash Size : 2MB I (43) boot: Enabling RNG early entropy source...

I’ve used several of these ESP32-S3 boards and haven’t had any issues so far. They’ve been reliable, easy to work with, and a good value for the price. These are based on the ESP32-S3 with 16MB flash and 8MB PSRAM, which is a nice bump over older ESP32 boards. Plenty of headroom for more complex projects, especially anything involving Wi-Fi, BLE, or heavier libraries. The dual USB-C ports are a nice touch. One is typically native USB (for flashing/CDC), and the other goes through a USB-to-UART bridge. Makes flashing and debugging straightforward without needing extra adapters. Wi-Fi and Bluetooth have been stable in my testing, and I haven’t run into any random disconnects or weird behavior. One small but useful note: the onboard LED appears to be on GPIO48 (not GPIO47 as some docs or examples suggest). If your blink sketch isn’t working, that’s probably why. Pros Reliable — I’ve used multiple boards with no failures Good specs (16MB flash + 8MB PSRAM) for the price Dual USB-C ports make flashing/debugging easy Works well with Arduino IDE and ESP-IDF Stable Wi-Fi and Bluetooth performance Compact and breadboard-friendly Cons Documentation is minimal (typical for these boards) Pin mappings (like the onboard LED) may not match common examples No labeling differences between USB ports on some revisions Bottom Line If you’re looking for a low-cost ESP32-S3 board with solid specs and reliable performance, these are a good choice. Just be prepared to double-check pin mappings if something doesn’t behave as expected. Quick Blink Example (Onboard LED) If your blink sketch isn’t working, try GPIO48 for the onboard LED: #define LED_PIN 48 void setup() { pinMode(LED_PIN, OUTPUT); } void loop() { digitalWrite(LED_PIN, HIGH); delay(500); digitalWrite(LED_PIN, LOW); delay(500); } If that doesn’t blink, try checking your board definition in the Arduino IDE and confirm the pin mapping, but on the boards I received, GPIO48 is correct. ... show more

    • Good quality ESP32-S3 microcontrollers.
Color: ESP32-S3
I’ve used two of these in prototype projects where I needed the Wifi for monitoring data. Tested all three and all work perfectly. Decent Wifi range as well for not having an external antenna. The S3 version of the ESP32 is worth it for me. Unless you need a super small for factor, these things are great. Just make sure whatever breakout board you have is for the S3 since it does have more pins. ... show more
