TIMI-130 – A breadboard color display with hundreds of pre-designed user interfaces

Tiny I2C, UART, or SPI displays are usually not difficult to connect to a breadboard with a few jumper cables, but Breadboard Mates TIMI-130 display makes that neater with a design made specifically for the breadboard, plus hundreds of pre-designed user interfaces/pages to simulate buttons, LED matrices, gauges, and other widgets. TIMI stands for Tiny Intelligent Modular Instrument, and TIMI-130 comes with a 1.3-inch color TFT IPS LCD, plus two 5-pin headers to power and connect the display to the breadboard through UART or I2C and update the widgets and values with simple commands. TIMI-130 specifications: Display driver – 4D Labs Pixxi-28 graphics processor with 14KB SRAM, 32KB flash Storage – 32MB flash Memory. Display – 240×240 pixel resolution TFT IPS LCD (non-touch). 2x 5-pin 2.54mm pitch headers with 3.3V (5V tolerant) serial UART interface (300 to 2187500 Baud). Master I2C (3.3V level) interface bus. 3x GPIO (3.3V level): 2x […]

Inkplate 6COLOR – A 5.8-inch e-paper color wireless display (Crowdfunding)

Inkplate 6COLOR is a 5.8-inch color e-paper display equipped with ESP32 WiSoC to provide WiFi and Bluetooth LE connectivity, and programmable with the Arduino IDE or MicroPython. We’ve covered Inkplate ESP32-based e-paper displays since Inkplate 6 was launched in 2019, and since then the company introduced a larger model and an upgraded variant with a touchscreen display and higher resolution. But so far, all were grayscale models, and Inkplate 6COLOR is the first to come with color, or more exactly 7 colors. Inkplate 6COLOR specifications: Wireless module with dual-core ESP32 processor, Wi-Fi 4 & Bluetooth 4.0 (BLE) connectivity External storage – MicroSD card socket Display – 5.8-inch, 600 x 448 e-paper display with 7 colors (Black, White, Red, Yellow, Blue, Green, Orange) 128 DPI 25 seconds refresh time (manufacturer); tested by Inkplate: 10 to 11 seconds USB – 1x USB Type-C port for programming and power Expansion – Headers for […]

More Allwinner F1C200s ARM9 boards: MangoPi R3 and CherryPi-F1C200S

I wrote about the Widora TINY200 board based on Allwinner F1C200s ARM9 processor with 64MB built-in RAM, up to 512MB NAND flash, LCD and camera interfaces in April 2020. I was just informed more similar Allwinner F1C200s boards had recently shown up with Widora MangoPi R3 that’s basically the same as TINY200, and CherryPi-F1C200S with similar dimensions and features, but a different ports arrangement. Let’s have a look at both. MangoPi R3 MangoPi R3 specifications are the same as the ones for Tiny200 board, but they selected the 128MB NAND flash storage option, and changed the USB-TTL chip: SoC – Allwinner F1C200s ARM926EJS processor @ 420 MHz (overclockable to 700 MHz) with 64MB DDR RAM Storage – 128MB NAND flash and MicroSD card slot Display I/F – 40-pin RGB565 display interface and 6-wire touch interface Camera I/F – 24-pin DVP camera interface compatible with OV2640, GC0328, etc. Audio – Onboard […]

Building a NanoPi M4V2 based All-in-One Linux PC running Armbian (Ubuntu/Debian)

At the end of my review of “RPI All-in-One” PC with Raspberry Pi 4, I noted the system also appeared to be compatible with NanoPi M4V2 single board computer. I’ve now tried it out, and assembling the board inside the 10.1-inch display is even easier than I initially thought. That means I now have a NanoPi M4V2 All-in-One PC running Ubuntu Hirsute or Debian Buster with XFCE desktop environment from Armbian, and most features work including the display and wireless connectivity, but I still have an issue with the touchscreen function. Here are the steps I followed initially: Download Armbian Buster XFCE image from Armbian and flash it to a microSD card with tools like USBimager. Insert the microSD card in the board Install the USB Type-C and HDMI-A adapters in the display. Insert the USB Type-C and HDMI port of the NanoPi M4V2 SBC into the adapters Install the […]

10.1-inch RPI All-in-One PC review with Raspberry Pi 4

A couple of months ago I received “RPI All-in-One”, a 10.1-inch touchscreen display for Raspberry Pi boards, listed the specifications, checked out the package content, installed a Raspberry Pi 4 inside the display before booting my new all-in-one (AiO) PC successfully. I’ve now had time to spend more time with the PC/display and see how it performs under various conditions. I also tested HDMI and USB-C input features with a laptop and mini PC. Fan or fanless operation? After updating Raspberry Pi OS, I ran sbc-bench.sh script together with rpi-monitor to see how the Raspberry Pi 4 with 1GB RAM would perform under load with the (noisy) fan enabled.
