Tiny Tri-color E-Ink display for Wemos D1 Mini board sells for $10

tri color E-Ink display for Wemos-D1 mini ESP8266 board

Wemos D1 Mini is one of my favorites ESP8266 boards with a cheap price, tiny form factor, and support for stackable expansion boards. Lolin has now launched a small 2.13-inch tri-color E-Ink display that is compatible with D1 mini, D1 mini Pro, and D32 Pro boards, and sells for just $9.90 plus shipping. Specifications: 2.13-inchTri-Color (red/black/white) ePaper/e-Ink display with 212×104 resolution Driver IC – Good Display UC8151D Connection to D1 mini, D1 mini Pro, D32 Pro via 10-pin connector Debugging – 8-pin unpopulated header with EPD signals (SPI, Reset, Busy…) 3.3V, GND You may wonder why the PCB reads “2.13 INCH e-Paper 250×122”, while the resolution is 212×104. That’s because the company probably reused the PCB from their 2.13-inch black and white e-Paper display with 250×122 resolution (IL3897 driver). The display can be programmed with Arduino using LOLIN_EPD, Adafruit_GFX, and Adafruit_BusIO libraries as explained in the Wiki. You’ll find three Arduino sketch samples on Github.

Watchy Pebble-like Smartwatch with E-paper display, ESP32 processor launched on Crowd Supply

Watchy

Pebble smartwatch was introduced in 2012 on Kickstarter. The Bluetooth smartwatch came with an E-Paper display, would connect to your Android smartphone or iPhone to receive notifications or other info, and the company also released an SDK for further customization. It was quite popular at the time having sold over one million units, the Pebble Time followed in 2015 with a color display, as well as other models. But despite selling millions of watches, the company folded in 2016, and the Pebble was discontinued after the intellectual property was purchased by Fitbit. Watchy is a new smartwatch that reminds me of the original pebble. It is based on ESP32 WiFi & Bluetooth SoC, equipped with a 1.54-inch E-Paper display with 200×200 resolution, and the usual accelerometer for activity tracking and gesture detection. Watchy key features and specifications: SIP – Espressif Systems ESP32-PICO-D4 system-in-package with ESP32 dual-core processor with Bluetooth LE 4.2/5.x and WiFi 4 connectivity, 4MB SPI flash Display – […]

Inkplate 10

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.

Year 2020 in review – Top ten posts and stats

CNX Software Year 2021

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 […]
