DIYables ESP32-S3-WROOM-1-N16R8 Dev Board and Solder-Free GPIO Expansion Board Combo
Click to zoom
Quick Overview
This DIYables combo bundles an ESP32-S3-WROOM-1-N16R8 development board with a solder-free 44-pin GPIO expansion breakout board. The dev board is built around the ESP32-S3-WROOM-1-N16R8 module, featuring a dual-core processor with 16MB flash, 8MB PSRAM, 512KB SRAM, and 384KB ROM, plus integrated 2.4GHz WiFi and Bluetooth 5 LE dual-mode wireless communication for IoT, AI, and automation projects.
The dev board has dual USB Type-C ports supporting both USB direct connection and UART download modes for programming, debugging, and flashing, with presoldered headers ready for immediate breadboard use. It also carries an onboard addressable RGB LED, plus RST and BOOT buttons for resetting and entering download mode.
The included expansion board lets you insert the dev board directly into its solder-free 44-pin socket. Rather than a plain pin breakout, every GPIO is routed to a color-coded GVS row — signal (yellow), voltage (red), and ground (black) grouped together — on both sides of the board, so three-wire sensors, servos, and modules plug straight in without a breadboard or splitting out power rails by hand. Dedicated 3.3V and 5V output pin blocks provide extra power taps, and an onboard AMS1117 regulator fed from a DC 2.1mm barrel jack (6.5–9V) powers the whole stack independently of USB — useful once a project moves off the bench.
This combo is ideal for rapid prototyping, IoT development, embedded systems learning, and educational projects using Arduino IDE, MicroPython, or ESP-IDF, giving you both the compute module and a convenient way to access every pin without extra hardware.
Key Features

※ NOTE THAT:
The GPIO expansion board works only with ESP32-S3 boards that have exactly 44 pins matching its socket layout, such as the included ESP32-S3-WROOM-1-N16R8 dev board. It is not a universal fit for all ESP32-S3 board variants.
If using the ESP32-S3 with analog sensors, configure the ADC with 11 dB attenuation to set the voltage reference range to handle up to 3.3V.
