Inkplate 5 – A 5.2-inch wireless e-paper display programmable with Arduino or MicroPython (Crowdfunding)

The team at Soldered Electronics has been designing Inkplate ESP32-based e-paper displays ever since the first 6-inch model was launched in 2019. The latest Inkplate 5 comes with a recycled 5.2-inch E-Ink (e-paper) display with refresh times of only 0.19 seconds, and programmable with the Arduino IDE or MicroPython firmware. The WiFi-connected display offers a 960×540 resolution, or 213 DPI pixel density, integrates an RTC with battery for accurate timekeeping, two buttons for power and wake/user, and I/O expansion via headers and an easyC/Qwicc connector. Inkplate 5 specifications: Wireless module – Dual-core ESP32 processor with Wi-Fi 4 & Bluetooth 4.0 (BLE) connectivity, 8MB flash, 4MB PSRAM External storage – MicroSD card socket Display – 5.2-inch, 960×540 e-paper display with 213 DPI pixel density Refresh times: full refresh in just 1.02s (1-bit and 3-bit) and partial refresh in 0.19s (1-bit) USB – 1x USB Type-C port for programming and power Expansion […]

$10 Arduino-programmable WCH CH552 macro keyboard is configurable from a web browser

The 4xMacropad is a low-cost, open-source hardware 4-key mechanical macro keyboard based on WCH CH552G 8051-compatible USB microcontroller and whose keys can easily be configured from a web browser generating an Arduino sketch. The CH55x family has been around for several years, and we first wrote about the sub-$2 CH551 Mini development board over 5 years ago, but CH552 variants are also found in more recent hardware such as the Turing Screen Screen information display and another rotary encoder shield with two mechanical keys. The 4xMacropad macro keyboard is another CH522 design, but it’s open-source. 4xMacroPad specifications: MCU – WCH CH552G 8051-compatible microcontroller @ 24 MHz with 16KB flash, 1.25KB SRAM USB – 1x mini USB port for power User input – 4x mechanical key switches with keypads Misc – Power LED, Mode switch (A or B), user button Power Supply – 5V via mini USB port The EasyEDA files, […]

Review of BIGTREETECH Pad 7 Klipper pad with Creality Ender-3 Pro S1 3D printer

Creality Ender-3 S1 Pro + BIGTREETECH Pad 7 Benchy 3D printing

I received the BIGTREETECH Pad 7 7-inch Klipper pad and tablet PC for review earlier this month. I’ve already tested it with a Raspberry Pi CM4 as a Linux tablet PC with touchscreen, and I’ve now reinstalled the BTT CB1 Allwinner H616 system-on-module to run the pre-install Klipper OS and connect the Pad 7 to a Creality Ender-3 Pro S1 3D printer. When I first booted the Pad 7 it ended up with an error message from Klipper complaining about a missing configuration file. I connected to WiFi and update all software packages, but it didn’t help. It’s just because the Pad 7 needs to be configured for a specific printer. We can do so through the web dashboard accessible through a web browser going to http://btt-pad7.local (unless you’d changed the hostname in the system) We’ve got the same error shown in the web interface as Klipper needs to be […]

Imagination IMG CXM is a small GPU with HDR support for TV boxes, wearables, and Smart Home appliances

Imagination IMG CXM is a power-efficient embedded GPU family with HDR support user interfaces, thus enabling OEMs to provide users the enriching visual experience they have come to expect but at a lower cost and with more design flexibility. The new CXM GPUs also deliver close to 50% performance density improvement over IMG BXM consumer GPUs, offer support for 10-bit RGBA/YUV to deliver a HDR graphical user interface with less visible banding, and integrate well with Imagination RISC-V CPUs. Three CXM GPUs are available: The CXM-2-64 with 2 pixels per clock (PPC) and 64 FLOPS per clock is the smallest GPU with native support for HDR The CXM-4-64 with 4 pixels per clock (PPC) and 64 FLOPS per clock targets mainstream products The CXM-4-128 with 4 pixels per clock (PPC) and 128 FLOPS per clock targets is better suited to “premium DTV solutions” All share the following features: 10-bit RGBA/YUV […]

SONOFF TX Ultimate Review – A smart touch wall switch with innovative features

SONOFF has been producing a wide range of new products over the years, and since the beginning of the year, the company introduced various new products and features including the iHost Smart Home Hub local hub which no longer requires cloud connectivity. The one we are going to review is the Ultimate Smart Touch Wall Switch (also known as the SONOFF TX Ultimate). SONOFF stated that they wanted to provide a new experience with their smart switch. Initially, we couldn’t imagine what new experiences a smart switch could offer. When we think of SONOFF, we usually associate it with affordable smart switches that are durable and perform as expected, not stylish or feature-rich devices. However, the SONOFF TX Ultimate comes as a complete package with light, color, sound, and touch. SONOFF has also expanded the touch area, so there’s no need to worry about missing the button while pressing it. […]
