Achei a ideia do #PocketTerm35 da #Waveshare interessante, apesar da ausência de um #trackball, mas a tela de 640x480, apesar de teoricamente adequada, reforça o retrocesso acumulado ao longo de décadas: apesar de todo o blá, blá, blá sobre convergência e dispositivos móveis, a realidade é outra, com desktop environments pesados demais para rodar em SBCs com 1 GB ou 2 GB de RAM (as poucas especificações minimamente acessíveis nos dias de hoje) e, em geral, pouca oferta de software convergente para algo além de relógios, cronômetros e calendários.

O #GNOME, por exemplo, ainda tem problemas para exibir a grade de aplicativos a 720p, caso o scaling seja de 125% ou maior para tornar a leitura mais fácil em tela pequenas (o que, na prática, reduz a resolução) e, em linhas gerais, parece muito pouco testado para cenários do tipo. E, claro, o GNOME não é exatamente o tipo de ambiente gráfico que você vai rodar num dispositivo, seja ARM, seja x86, com 1 GB ou 2 GB de RAM.

Mesmo aplicativos mais antigos e fora dos holofotes, como #Abiword e #Gnumeric realisticamente esperam 800x600 de resolução. É compreensível, mas problemático. Simplesmente não temos quase nada que rode em 640x480.

Dear #waveshare , fuck you for such a messed up pin labeling. Who on Earth would've imagined that D5 is a GPIO8?

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

I finally wrapped up my custom mini #cyberdeck build last night. Uses a #waveshare ESP32-S3 touchscreen and a mini "OS" built using #circuitpython I wrote a blog post about the build (including links to download the #3dprint models and code) https://andywarburton.co.uk/post/gr3ml1n-a-compact-handheld-cyberdeck-built-for-chaos

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
