ESP32-C5-LCD-1.47: A Thumb-Sized Dual-Band Wi-Fi 6 IoT Board

The ESP32-C5 Dev Board Puts Dual-Band Wi-Fi 6 in Your Fingertips

Every so often a board comes along that makes you do a double-take at just how much got packed into the footprint. The ESP32-C5-LCD-1.47, announced by Espressif on July 3, 2026, is exactly that kind of board. This ESP32-C5 dev board measures roughly 36.5 x 20.5 mm, small enough to pinch between two fingers, yet it delivers dual-band Wi-Fi 6 plus a full spread of smart-home radios. For anyone prototyping IoT, this dual-band Wi-Fi 6 IoT board is a lot of capability in a very small package.

At its heart sits the ESP32-C5FH4, a single-core 32-bit RISC-V processor running at 240 MHz, paired with a low-power core at 40 MHz for the light-duty background work that keeps power draw sensible. You get 384 KB of SRAM and 4 MB of flash on board. RISC-V continues its steady march into the maker mainstream, and having it in a chip this affordable and this connected is exactly why the architecture keeps winning fans.

Dual-Band Wi-Fi 6 Plus Thread, Zigbee, and Matter

The wireless story is the real headline. This little single board computer carries dual-band Wi-Fi 6, covering both 2.4 GHz and 5 GHz on 802.11ax, which is still relatively rare in a board this size. Add Bluetooth 5 LE and IEEE 802.15.4 with Zigbee 3.0, Thread 1.3, and Matter support, and you've got a genuinely versatile smart-home hub or endpoint in the palm of your hand.

That combination matters. Thread and Zigbee let the board talk to mesh sensor networks, Matter gives it a common language across ecosystems, and dual-band Wi-Fi 6 handles the high-bandwidth uplink. Building a Matter bridge, a Thread border-router experiment, or a Zigbee sensor node? This one chip can wear all those hats.

A Tiny Color Screen and Plenty of I/O

Despite its size, the board doesn't skimp on the practical stuff. There's a 1.47-inch color TFT LCD at 172x320 driven by the familiar ST7789 controller, ideal for status readouts, tiny dashboards, or simple UI. A microSD slot handles local storage and logging, and USB Type-C keeps flashing and power modern and reversible.

For makers, the I/O count is what seals it. You get 14 GPIO broken out via headers, 5 ADC inputs, and a WS2812 addressable RGB LED for status blinks or a little flair. Bus support is broad too: I2C, SPI, PWM, I2S, UART, and CAN are all on tap, so this board slots into sensor rigs, audio projects, and even automotive-style CAN experiments without extra glue hardware.

Put it together and the ESP32-C5-LCD-1.47 reads like a Swiss Army knife for edge and smart-home prototyping: RISC-V compute, a bright color screen, generous I/O, and a radio stack that speaks nearly every protocol worth knowing. Espressif hasn't disclosed pricing yet, so keep an eye out as availability details follow. For makers who want a thumb-sized dual-band Wi-Fi 6 IoT board ready for Matter, this one is well worth bookmarking.
