Clawdmeter is a DIY ESP32-S3-powered desk dashboard that displays Claude Code token usage on a 2.16-inch AMOLED screen so you know when you’re about to reach the limits in real time.It’s mostly a firmware project since it relies on off-the-shelf hardware (Waveshare ESP32-S3-Touch-AMOLED-2.16). It leverages the LVGL library for its graphics user interface, the NimBLE stack for Bluetooth LE (BLE) communication, and also functions as a HID keyboard for shortcuts using the buttons from the unit.We previously covered Waveshare ESP32-S3-Touch-AMOLED-1.8 with a 1.8-inch display, but never the 2.16-inch variant, so let’s have a quick look at the hardware first.ESP32-S3-Touch-AMOLED-2.16 specifications:
Wireless MCU – Espressif Systems ESP32-S3R8
CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration.
Memory – 512KB RAM, 8MB PSRAM
