Merlot is an open-source hardware tricolor wireless E-paper display

paperd.ink Merlot is a tricolor E-paper display with an open-source hardware control board based on ESP32 wireless SoC that is programmable with Arduino, MicroPython, or the ESP-IDF framework. We first wrote about the paperd.ink 4.2-inch ESP32-based monochrome e-Paper display last year, but the company has now refined its design with the “paperd.ink Classic” replacing the 3D printed enclosure with a vacuum cast enclosure and adding a 1,900 mAh battery. They also launched a new model, the Merlot, based on the same design but with a display supporting three colors: black, white, and red. Merlot specifications: Wireless module – ESP32-WROOM-32 module with ESP32 dual-core processor, 4 MB SPI flash, 2.4 GHz WiFi 4 & Bluetooth LE connectivity Storage – MicroSD card slot for storing images, files, etc Display – 4.2″ tricolor e-Paper display with 400 x 300 resolution; full refresh: ~ 17 seconds; partial update: also 17 seconds… USB – 1x […]

Banana BPI-Bit-S2 BBC Micro:bit compatible board supports WiFi

Banana BPI-Bit-S2 is a board for the education market that’s compatible with the BBC Micro:bit V2, but offers WiFi connectivity instead of Bluetooth LE through an Espressif Systems ESP32-S2 wireless microcontroller. The BPI-Bit-S2 succeeds the earlier Banana Pi BPI-Bit with ESP32 WiFi & BLE microcontroller that was a closer match to the original BBC Micro:bit than the new ESP32-S2 board for which I see little benefit, except for the slightly lower price tag. Banana BPI-Bit-S2 specifications: Wireless MCU – Espressif Systems ESP32-S2FN4R2 single core LX7 microcontroller with 320 kB SRAM, 2MB PSRAM, 4MB flash, 2.4 GHz WiFi connectivity LEDs – 25x RGB LED matrix USB – 1x USB Type-C port for power and programming Sensors – 2x light sensors, 1x thermistor sensor Expansion – 3x I/O rings, 3V/GND rings, 20-pin edge connector (compatible with BBC Micro:bit V2 design) with up to 16x GPIO, I2C, SPI, 3.3V, and GND Misc – […]

ArduCam Mega – A 3MP or 5MP SPI camera for microcontrollers (Crowdfunding)

ArduCam Mega is a 3MP or 5MP camera specifically designed for microcontrollers with an SPI interface, and the SDK currently supports Arduino UNO and Mega2560 boards, ESP32/ESP8266 boards, Raspberry Pi Pico and other boards based on RP2040 MCU, BBC Micro:bit V2, as well as STM32 and MSP430 platform. Both cameras share many of the same specifications including their size, but the 3MP model is a fixed-focus camera, while the 5MP variant supports autofocus. Potential applications include assets monitoring, wildfire monitoring, remote meter reading, TinyML applications, and so on. ArduCam Mega specifications: Camera Type 3MP with fixed focus 5MP with auto-focus from 8cm to infinity Optical size – 1/4-inch Shutter type – Rolling Focal ratio 3MP – F2.8 5MP – F2.0 Still Resolutions 320×240, 640×480, 1280×720 x 1600 x1200x 1920 x 1080 3MP – 2048 x 1536 5MP – 2592×1944 Output formats – RGB, YUV, or JPEG Wake-up time 3MP – […]

T-Camera S3 – An ESP32-S3 board with camera, display, PIR motion sensor, and microphone

LilyGO has launched a new ESP32-S3 WiFi & BLE camera board with the T-Camera S3 also featuring a small display, a PIR motion sensor, and a microphone, as well as an optional plastic shell. The T-Camera S3 is an evolution of the TTGO T-Camera ESP32 board introduced in 2019 with many of the same features, but the ESP32 microcontroller has been replaced with an ESP32-S3 microcontroller with vector extensions that makes it suitable for machine learning and computer vision applications. The new board also comes with a larger 16 MB SPI flash, more I/Os, and a few other small changes. T-Camera S3 specifications: ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ 240 MHz (Note: this SKU is not listed in the official ESP32-S3 datasheet) with 2.4 GHz 802.11n WiFI 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash Camera – 2MP […]

OpenPLC open-source Programmable Logic Controller Suite works with Arduino, ESP8266/ESP32, Raspberry Pi, etc.

OpenPLC is an open-source, free-to-use Programmable Logic Controller Suite, compliant with the IEC 61131-3 standard, and working with a range of hardware platforms such as Arduino, ESP8266/ESP32, Raspberry Pi SBCs, as well as Windows and Linux machines. When Arduino unveiled the Arduino PLC IDE, we noted the languages defined by the IEC 61131-3 standard were licensed, and the PLC key for the Portenta Machine Control unit sold for $17.60. One reader complained about the high license cost per device, but Massimo Banzi, the co-founder of the Arduino project, replied it was cost-effective for smaller deployments: Actually it’s not that much money compared to the cost of other PLC software (thousands of dollars per seat!). This model helps small companies with not that many devices.. It’s possible to negotiate bulk licenses for companies. But there’s also another option with OpenPLC open-source PLC suite that does not require any license fee. That’s […]
