Dustin Watts developed FreeTouchDeck software to interface with Windows, macOS, Linux computers and boards over Bluetooth LE using an ESP32 board connected to a touchscreen display. So far, he used off-the-shelf parts, but he has now decided to create his own hardware with ESP32 TouchDown open-source hardware board equipped with a 480×320 TFT display. ESP32 TouchDown specifications: Wireless Module – ESP32-WROOM-32D with ESP32 dual-core WiFi & Bluetooth processor, 4MB flash, PCB antenna Display – 3.5-inch 480*320 TFT screen based on ILI9488 driver connected over SPI mode, plus FT6236 Capacitive Touch Controller Storage – MicroSD card reader USB – 1x USB-C port Expansion Header with I2C, SPI, 7x GPIO, 3.3V and GND Stemma / JST-PH I2C connector Debugging – CP2102 USB-to-UART IC Misc – Piezo speaker, Power & Charge LEDs, on/off switch, boot and reset buttons, Power Supply 5V via USB-C 2-pin JST connector for battery APK2112 3.3V regulator MCP73831 battery management IC Battery voltage divider connected to GPIO35 OSHWA certification […]
Inkplate 6 is an ESP32 powered wireless e-Paper Display based on a recycled Kindle E-reader display, and that e-Radionica launched in December 2019 via a crowdfunding campaign. The company says backers were “happy about the versatility and simplicity of the display” but wished for a larger display, a faster refresh rate, and extra features. This gave birth to an upgraded version: Inkplate 10. The new ESP32 wireless display comes with a recycled 9.7-inch display with 1200 x 825 resolution, up to 38% faster refresh rates, as well as extra GPIO pins, an RTC clock, a USB Type-C port, and lower power consumption. Inkplate 10 specifications: Wireless module – ESP32 WROVER module with dual-core ESP32 processor with Wi-Fi & Bluetooth 4.0 (BLE) connectivity, 8MB PSRAM, 4MB flash External storage – MicroSD card socket Display – 9.7-inch, 1200 x 825 e-paper display with support for grayscale, partial updates, and quick refresh cycles: 1.61 second refresh time in black & white mode 1.81 […]
It’s this time of the year when we look back at what happened, and what may be next. 2020 did not pan out as planned in more ways than one, but there were still some interesting developments. Based on 2019 announcements, 2020 was promising to be an exciting year for Amlogic and Rockchip with the expected launch of RK3588 and S908X high-end processors for 8K capable devices, but we’ll have to wait for 2021 for this to happen. Instead, the most interesting processor of the year from the Allwinner, Amlogic, and Rockchip offerings was probably Amlogic S905X4 processing adding AV1 hardware decoding. As pointed out in our “RISC-V 2020 highlights” post, it was a fairly eventful year for RISC-V architecture, although there’s still a long road ahead, especially for application processors. We had seen some general-purpose and Bluetooth RISC-V MCUs in 2019, but 2020 saw the launch of the first WiFi IoT RISC-V chips with ESP32-C3 and BL602, Alibaba making […]
Earlier this week, we covered Wireless Tag’s Industio 7-inch smart display powered by a SigmaStar SSD201 32-bit Arm Cortex-A7 processor and offering both Ethernet and WiFi 4 connectivity. If you’d like a 64-bit processor, a much larger display size, and faster wireless connectivity, Innocomm has just introduced the “Foenix Touch Console” 21.5-inch open-frame touch computer based on the same MediaTek MT8167A quad-core Cortex-A35 processor as found in the PlayStation Classic, and capable of Ethernet and WiFi 5 (AC) networking. Foenix iCOM1019 touch console preliminary specifications: SoC – MediaTek MT8167A quad-core Cortex-A35 processor @ up to 1.5 GHz with PowerVR GE8300 GPU System Memory – 2GB RAM Storage – 8GB storage, MicroSD card slot Display – 21.5-inch PCAP touchscreen display with 1920×1080 resolution Video Output – Optional HDMI 1.4a Audio – 2-channel 6W amplifier, 2x digital microphones, 3.5mm 4-pole audio jack Camera – Optional 2MP front-facing camera Connectivity 10/100M Ethernet (RJ45) 802.11a/b/g/n/ac WiFi 5 2×2 MIMO Bluetooth 4.2 and 5.0 LE […]
We previously covered the $10 Industio IDO-SOM2D01 module based on SigmaStar SSD201 Cortex-A7 processor with 64MB RAM built-in, 128MB SPI NOR flash, and designed for full HD smart displays. Today I learned Industio was the design team of system-on-module for Wireless Tag, and the latter is the only distributor of Industio branded products. The company also informed us about Industio IDO-SBC2D70 7-inch smart display based on the aforementioned SSD201 or SSD202 module and connected over Ethernet or WiFi. Industio IDO-SBC2D70 smart display specifications: SoM – Industio IDO-SOM2D01 with SoC – SigmaStar SSD201/SSD202 dual-core Cortex-A7 processor @ 1.2 GHz with 2D GPU, 64MB DDR2 (SSD201) or 128MB DDR3 (SSD202) Storage – 128MB SPI NAND flash (option up to 512MB) Video Decoder – H.264/H.265 up to 1920×1080 @ 60 fps Dimensions – 2.95 x 2.95 cm Storge – MicroSD card socket (SDIO 2.0) Display – 1024 x 600 IPS RGB module by default (supports up to 1920 x 1080 @ 60 Hz) […]
We’ve very recently covered M5paper IoT development kit based on ESP32 WiSoC, and equipped with a 4.7-inch touchscreen e-Ink display together with a 1,150mAh battery all nicely packed into an enclosure. It looks great, but costs $69, so if you’d like to integrate this type of ESP32 connected display into your own project at a lower cost, you may be interested in TTGO T5 4.7-inch e-Paper display with 16 gray levels fitted with an ESP32-WROVER-E module with 16MB flash, and 8MB PSRAM. TTGO T5 key features and specifications: Display 4.7-inch ePaper display with 960×540 resolution, 16 gray levels , partial refresh support 6-pin FPC touchscreen connector Wireless module – ESP32-WROVER-E with ESP32-D0WDQ6 V3 dual-core processor, 16MB flash, 8MB PSRAM USB – 1x USB-C port Expansion – 4-pin connector with GPIOs, GND, 3.3V Misc – 1x reset button, 4x user buttons Debugging – USB-C port connected to USB to TTL CP2104 chip Power Supply 5V/1A via USB-C port 18650 battery metal […]
We’ve already seen ESP32 platforms with a color display such as M5Stack, but MorphESP 240 is kind of cute with a 1.3-inch color display, features the more recent ESP32-S2 WiFi processor, and supports battery power & charging. MorphESP 240 specifications: Wireless Module – ESP32-S2-WROOM with Espressif Systems ESP32-S2 single-core 32-bit Xtensa LX7 microprocessor up to 240 MHz with 128 KB ROM, 320 KB SRAM, 16 KB SRAM in RTC, 4MB SPI flash, 802.11 b/g/n 2.4 GHz Wi-Fi connectivity Display – Onboard 1.3-inch ST7789 display with 240 x 240 resolution, connected over SPI USB – 1x Micro USB port for power/charging and programming Expansion – 16-pin and 24-pin headers with GPIO, I2C, UART, SPI, USB, and power signals Misc – WS2812B RGB LED connected to IO16, Reset button, boot mode switch, battery on/off switch Power Supply 5 V to 3.3 V regulator to feed additional modules JST connector for a battery plus a USB charging module Dimensions – 89 x 28 […]
The Raspberry Pi Foundation has recently launched the Raspberry Pi 4 keyboard computer with impressive performance thanks to a well-designed cooling solution, and I think it’s a great tool for kids (and adults) who may want to carry a Raspberry Pi around. However, you’d still need a display in each location, so until the foundation releases the Raspberry Pi 4000 laptop next year (full disclose: I made that up!), it might be cool to have a portable display coming with the keyboard PC. That’s what Waveshare is offering with two kits combining a Raspberry Pi 400 together with a 7-inch or 13.3-inch HDMI touchscreen display and other accessories. Not quite as portable as a laptop but it gets close. Here’s the full list of accessories in the kits: Raspberry Pi 400 Kit with keyboard PC with UK keyboard (sadly the only layout option for now), power supply, HDMI cable, preloaded microSD card with Raspberry Pi OS, mouse, and Beginner guide.
