Keyboardio Model 100 wooden keyboard runs open-source Arduino firmware (Crowdfunding)

Are you bored with keyboard news yet? Keyboardio Model 100 does not quite look like most keyboards though. It’s basically a piece of art with an enclosure made of walnut or maple hardwood, and designed as an ergonomic keyboard with left and right parts with a total of 64 mechanical switches with RGB LEDs and custom-sculpted keycaps. Keyboardio Model 100 also runs Kaleidoscope open-source firmware programmed in the Arduino IDE, and can be customized by the user with Chrysalis open-source, cross-platform graphical configuration tool. The community is also working on porting QMK firmware to the keyboard. The Keyboardio Model 100 ships with QWERTY keycaps, but alternative keycap sets with Dvorak, Colemak, Linear A, or blank legends are available as a add-on. Other accessories include a 1.5 USB-A to USB C cable for connection to the host, a 10cm RJ45 interconnect cable and a 1m RJ45 interconnect cable to connect the […]

MicroMod Teensy brings Teensy 4.0 board to M.2 form factor

Teensy 4.0, a low-cost board based on NXP i.MX RT1062 Arm Cortex-M7 crossover processor, is now getting a little brother with MicroMod Teensy following the same M.2 form factor as other Sparkfun MicroMod boards. Born from a collaboration between PJRC and Sparkfun, MicroMod Teensy has essentially the specs of Teensy 4.0 but with larger flash memory, and the board will be fully supported by the Teensyduino add-on to the Arduino IDE as noted by Paul Stoffregen on Twitter. MicroMod Teensy specifications: SoC – NXP i.MX RT1062 Arm Cortex-M7 processor at 600 MHz with 1024KB RAM (512KB is tightly coupled), Storage – 16MB serial flash (instead of 2MB on Teensy 4.0) M.2 MicroMod connector with USB Device up to 480Mbit/sec: Capable of enumerating as a USB keyboard, mouse, joystick, MIDI, audio, and more USB Host up to 480Mbit/sec: Capable of interfacing to USB flash drives, mice, keyboards, and more 7x Serial […]

LILYGO Mini E-Paper Core combines ESP32 with 1.02-inch ePaper Display in 3D printed enclosure

LILYGO Mini E-Paper Core is another ESP32-based e-Paper display by LILYGO, but it’s a really tiny 1.02-inch e-Paper display housed in a 3D printed enclosure that reminds me of M5Stack Core with a 2-inch TFT LCD. The tiny low-power display also offers a MicroSD card socket, a reset button, a three-way user button, as well as headers for GPIOs, ADC, DAC, SPI, and more. LILYGO Mini E-Paper Core specifications: Wireless SiP – ESP32-PICO-D4 system-in-package with ESP32 dual-core processor, 4MB Flash, 2.4 GHz WIFi 4 & Bluetooth connectivity Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 resolution USB – 1x USB Type-C for power and programming Expansion 7-pin 2.54mm pitch header with 5x GPIO, 2x ADC, 2x DAC, 3.3V, and GND 8- pin 2.54mm pitch header with 4x GPIO, SPI, 1x ADC, 5V, VBUS, VBat, and GND Misc – Three-way toggle button connected to G36, G0, […]

paperd.ink 4.2-inch ESP32-based e-Paper display ships with a 3D printed enclosure (Crowdfunding)

We’ve covered a fair amount of connected e-Paper/e-Ink displays based on ESP32 WiFi & Bluetooth SOC including several Inkplate displays, with the latest Inkplate 6Plus model including a touchscreen, TTGO T5 displays with small sizes, or even the fully enclosed M5Paper ESP32 IoT development kit with a 4.7-inch touchscreen e-Paper display. There’s also Watchy ESP32 smartwatch with a 1.54-inch display if you really need something small. But here’s another option courtesy of Rohit & Prasad, two young engineers from India, with the paperd.ink 4.2-inch ESP32-powered e-Paper display that ships with an optional 3D printed enclosure. paperd.ink display 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″ monochrome e-Paper display with 400 x 300 resolution; 3s for full refresh; partial refresh supported USB – 1x […]

Picovoice offline Voice AI engine now works on Arduino

Last year, I wrote about Picovoice support for Raspberry Pi enabling custom wake-word and offline voice recognition to control the board with voice commands without relying on the cloud. They used ReSpeaker 4-mic array HAT to add four “ears” to the Raspberry Pi SBC. I also tried to generate a custom wake-word using the “Picovoice Console” web interface, and I was able to use “Dear Master” within a few minutes on my computer. No need to provide thousands of samples, or wait weeks before getting a custom wake-word. It’s free for personal projects. But the company has now added Picovoice to Arduino, or more exactly Arduino Nano 33 BLE Sense powered by a Nordic Semi nRF52480 Arm Cortex-M4F microcontroller, and already equipped with a digital microphone, so no additional hardware is required for audio capture. To get started, you’d just need to install the Picovoice Arduino library, load the sample […]

BastWAN Feather-compatible LoRaWAN board features RAK4260 Microchip R34 module

We’ve previously written about a Feather-compatible LoRaWAN board equipped with RAK4260 module based on Microchip R34 LoRa SIP called Penguino Feather. It appears somebody, namely Electronic Cats based in Mexico, decided to design an almost identical board with BastWAN. Let’s see if there are any differences besides the cheaper price. BastWAN specifications: LoRa module – Rak wireless RAK4260 module with: SiP – Microchip SAML21 Arm Cortex M0+ MCU @ 48 MHz, 32 KB RAM, 256 KB Flash, Semtech SX1276 LoRa Connectivity Frequency Range – 862 to 1020 MHz High level of accuracy and stability (32MHz TXCO) Max Tx Power: 20dBm; Max Sensitivity: -148dBm; Rx Current: 17mA (typical) Compliant with LoRaWan 1.0.2 Antenna – SMA and u.FL (IPEX) antenna connector I/Os – Feather headers with 20x IO pins including PWN, serial, I2C, SPI, 6x 12-bit ADC, 1x 10-bit DAC HW security – ATECC608A crypto authentication chip Programming and debugging 10-pin 4-pin […]
