<\/a><\/p>\nWe previously covered Waveshare ESP32-S3-Touch-AMOLED-1.8<\/a> with a 1.8-inch display, but never the 2.16-inch variant, so let\u2019s have a quick look at the hardware first.<\/p>\n ESP32-S3-Touch-AMOLED-2.16 specifications:<\/p>\n Wireless MCU \u2013 Espressif Systems\u00a0ESP32-S3R8<\/a><\/p>\n CPU \u2013 Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration. Storage<\/p>\n 16MB NOR flash Display<\/p>\n 2.16-inch AMOLED display Audio<\/p>\n ES8311 low-power mono audio codec USB \u2013 1x USB Type-C port for power and programming Power, Boot, and User (GPIO18) buttons Power<\/p>\n 5V via USB-C port Dimensions \u2013 46 x 46 x 22.5 mm<\/p>\n Waveshare provides support for the ESP-IDF framework and the Arduino IDE, and offers various code samples for each, including the ESP-Brookesia firmware. They also published tutorials to use XiaoZhi AI, OpenClaw, and ESP-Claw with the device. You\u2019ll find all the resources to get started on the documentation website<\/a>.<\/p>\n Back to the ClawdMeter project. It pairs with your laptop over Bluetooth, displays pixel-art Clawd animations that speed up as Claude Code usage rate climbs, shows stats, and the two side buttons send Space and Shift+Tab over BLE HID for Claude Code\u2019s voice mode and mode-toggle shortcuts.<\/p>\n The firmware is written in C using Platform IDE with the help of Claude. The code looks decent and uses constants instead of hard-coded coordinates, as recently seen in some other projects<\/a>. That means you can probably port it fairly easily to other ESP32 platforms with different display resolutions.<\/p>\n If you\u2019d like to reproduce the exact same setup, you can purchase the ESP32-S3-Touch-AMOLED-2.16 controller for about $30 on AliExpress<\/a>, Amazon ($40.99)<\/a>, or the Waveshare store<\/a> with or without a battery (saves about $2). However, as noted by various X users<\/a>, there are various ways to implement such a Claude Code meter, for instance, a taskbar app or other widget running on the host, or an app to show the usage on a USB information display<\/a>. More details about the ClawdMeter can also be found on the project\u2019s website<\/a>.<\/p>\n Via Adafruit<\/a><\/p>\n Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.<\/p>\n Support CNX Software!
