Waveshare's ESP32-C6-LCD-1.47 Is a Development Board for the World's Tiniest Smartphone
Compact 1.47" color display on the front is ideal for human-machine interface projects, the company claims.
Embedded and hobbyist electronics specialist Waveshare has launched a development board based around the Espressif ESP32-C6 microcontroller, cramming a smartphone-like display into just 1.47" β while retaining breadboard compatibility.
"[The] ESP32-C6-LCD-1.47 integrates LCD display, onboard TF Card [microSD Card] slot and multiple peripheral interfaces," Waveshare writes of its latest development board. "[The] onboard 1.47" LCD screen can smoothly run GUI [Graphical User Interface] programs such as LVGL. Combined with various peripheral interfaces, [it is] suitable for the quick development of the HMI [Human-Machine Interface] and other ESP32-C6 applications."
The processor at the heart of the compact development board, brought to our attention by CNX Software, is Espressif's ESP32-C6, which includes a single 32-bit RISC-V core running at up to 160MHz and a secondary low-power RISC-V core running at up to 20MHz. There's 512kB of static RAM (SRAM), plus 16kB of low-power SRAM for the secondary core, 320kB of on-chip flash and 4MB of additional flash, plus a radio delivering single-band Wi-Fi 6 and Bluetooth 5 Low Energy (BLE) connectivity.
The front of the board is dominated by its LCD display, a 1.47" rounded-edge rectangular panel with a 172Γ320 resolution and 262,000 colors. To look at from the top, the result is very smartphone-like β until you get a sense of just how tiny the device is in the hand. There's no battery, though, and flipping the board over reveals unpopulated breadboard-friendly pin headers for general-purpose input/output (GPIO) connectivity β including pulse-width modulation (PWM) on all pins and analog inputs on six.
The board is available to buy on the Waveshare store for $11.99 before volume discounts.
