ESP32-C5 devkit offers 2.8-inch capacitive touch display, dual-band Wi-Fi 6, Bluetooth 5 LE, LiPo battery support

Last week, I wrote about the ESP32-C5-LCD-1.47 as one of the first ESP32-C5 devkits with a built-in display enabling dual-band WiFi 6 connectivity for IoT and HMI projects. However, one reader lamented the lack of touch-capable screens, at which point kwchow pointed to the ESP32-C5-Touch-LCD-2.8 model offering just that by pairing an ESP32-C5 with a 2.8-inch IPS display with capacitive touch and 320×480 resolution. The new board also features a microSD card slot, a USB-C port for power and programming, a built-in microphone and a speaker connector, a few sensors, and various I/Os connectors for expansion. Let’s have a closer look. ESP32-C5-Touch-LCD-2.8 specifications: Wireless module – Espressif Systems ESP32-C5-WROOM-1-N32R8 SoC – ESP32-C5HR8 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, 8MB PSRAM Storage – 320 KB ROM Wireless […]

BIGTREETECH Panda Sense Pro 8-in-1 smart air quality monitor works with Home Assistant and Klipper for 3D printers

BIGTREETECH Panda Sense Pro 8-in-1 Air Quality Monitor for 3D Printers

BIGTREETECH (BIQU) has introduced the BIQU Panda Sense Pro, an 8-in-1 smart air quality monitor designed for 3D printing environments such as home workshops, maker spaces, and print farms. It continuously measures airborne particles, gases, temperature, and humidity, helping users monitor indoor air quality while printing. The device also integrates with Klipper-based printers and smart home platforms, making it suitable for both standalone monitoring and automated environmental control. It combines laser particle, NDIR CO₂, and electrochemical formaldehyde sensors to monitor PM2.5, PM10, CO₂, HCHO, eTVOC, AQI, temperature, and humidity in real time. The monitor features a 3.5-inch 480×320 TFT display, 2.4 GHz Wi-Fi with MQTT, USB Type-C power, 24-hour and 30-day data logging, and upcoming app-based remote monitoring. It integrates with Moonraker (Fluidd/Mainsail) and Home Assistant for automation, such as controlling fans or air purifiers based on sensor readings. The enclosure files are open-source, which means you can customize and […]

ESP32-C5 dual-band WiFi 6 and Bluetooth LE IoT board features 1.47-inch color LCD

We’ve covered plenty of connected displays based on ESP32 chips over the years, but the Waveshare ESP32-C5-LCD-1.47 is a little different, since it’s the first to feature an ESP32-C5 chip for dual-band WiFi 6 connectivity. It’s basically based on the ESP32-C6-LCD-1.47 design, but replaces the ESP32-C6 supporting 2.4 GHz WiFi 6 with an ESP32-C5 capable of handling both 2.4 GHz and 5 GHz WiFi 6. Other features mostly remain the same: a 1.47-inch 262K-color display with 320 x 172 resolution, 4MB of flash, an RGB LED, a microSD card slot, and two 9-pin headers for GPIO expansion. Waveshare ESP32-C5-LCD-1.47 specifications: Wireless MCU – Espressif Systems ESP32-C5FH4 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, 4MB flash Wireless Connectivity Dual-band (2.4GHz/5 GHz) 802.11ax WiFi […]

Titan Mini is a smaller Renesas RA8P1-based Edge AI board for RT-Thread RTOS development

The Titan Mini is a smaller and somewhat cheaper version of the RA8P1 Titan board introduced in 2025 for AIoT applications and RT-Thread RTOS development. It still features a Renesas R7KA8P1 Cortex-M85/M33 microcontroller with an Arm Ethos-U55 NPU, but comes with lower-capacity memory and storage chips (32MB SDRAM and 8MB QSPI flash), drops the RJ45 Ethernet ports with a single FPC Ethernet connector, among other cost-saving measures. The only benefit I see besides the smaller size and slightly lower price is the presence of a microphone and a speaker connector for audio applications. Titan Mini specifications: SoC – Renesas RA8P1 (R7KA8P1) MCU cores Arm Cortex-M85 clocked at 1 GHz with Helium MVE (M-Profile Vector Extension) with 32KB I/D caches; 7300+ CoreMarks Arm Cortex-M33 clocked at 250 MHz with 32KB I/D caches GPU – D/AVE 2D drawing engine NPU – Arm Ethos-U55 NPU delivering 256 GOPS at 500 MHz Memory – […]
