$60 kit transforms the Raspberry Pi 4/5 into a DIN Rail industrial computer with isolated RS232, RS485, and CAN Bus

Waveshare's "Isolated RS232 / RS485 / CAN / CAN FD Expansion Board For Raspberry Pi" kit transforms your Raspberry Pi 4B or 5 into an industrial computer with a DIN rail or wall mount enclosure. The solution also provides access to isolated interfaces, including two RS485, RS232, CAN FD, and CAN Bus interfaces, as well as 7-36V DC input through screw terminals. The complete solution also benefits from the Raspberry Pi's Gigabit Ethernet, four USB ports, and full-size HDMI port (via adapter), as well as support for Raspberry Pi HAT and PCIe expansion boards for NVMe SSD, an additional GbE port, 4G LTE/5G cellular, etc... Specifications: Compatible SBCs - Raspberry Pi 4B and Raspberry Pi 5 Host interface - SPI + UART Isolated industrial interfaces via screw terminals 1x CAN FD with 5kbps ~ 8 Mbps baudrate via MCP2518FD + MCP2562FD chips 1x CAN Bus with 5kbps ~ 1 Mbps

Clawdmeter – A DIY ESP32-S3 desk dashboard for Claude Code token usage monitoring

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 ROM – 384KB Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE Storage 16MB NOR flash MicroSD card slot

ESP32-C5-WIFI6-KIT dual-band WiFi IoT board offers up to 32MB flash, 8MB PSRAM, onboard or external WiFi antenna

Waveshare ESP32-C5-WIFI6-KIT development kit looks similar to the official Espressif Systems ESP32-C5-DevkitC-1 board, but offers a wider range of options, including different PSRAM and flash capacities, and onboard or external antenna selection. While the official devkit ships with 8MB PSRAM, 4MB SPI flash, and a PCB antenna, the Waveshare board is offered with up to 8MB PSRAM, 16MB or 32MB flash, and either a PCB and external antennas. It also adds battery support and can be ordered with or without pre-soldered headers. Waveshare ESP32-C5-WIFI6-KIT specifications: Wireless module - ESP32-C5-WROOM-1 or ESP32-C5-WROOM-1U SoC – ESP32-C5 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for power-sensitive applications Memory – 384 KB SRAM on-chip Storage – 320 KB ROM Connectivity Dual-band (2.4GHz/5 GHz) 802.11ax WiFi 6, with 802.11b/g/n WiFi 4 standard fallback 20MHz bandwidth for the 802.11ax mode 20/40MHz bandwidth

UGV Beast – An off-road tracked AI robot built for Raspberry Pi 4/5

Waveshare UGV Beast is an off-road robot with tracked wheels designed for Raspberry Pi 4 or 5 SBC handling AI vision and strategy planning, while an ESP32 sub-controller takes care of motion control and sensor data processing. If the design feels familiar, it's because it's a variant of the UGV Rover unmanned ground vehicle we covered in 2024, which replaces the six wheels of the original model with two continuous tracks, as found in military tanks, for better driving in difficult terrain. Waveshare UGV Beast specifications: Supported SBCs – Raspberry Pi 4B or Raspberry Pi 5 Multi-function driver board/sub-controller Main SoC - ESP32 wireless microcontroller with WiFi, Bluetooth, ESPNOW connectivity Motor drivers - 2x TB6612FNG chips Peripheral interfaces 4x motor control connectors 2x servo connectors Lidar USB (4-pin) and UART (USB-C) connectors 2x 4-pin I2C connectors Sensor - 9-axis attitude sensor (ICM20948) for image stabilization Misc - EN and user
