microByte ESP32 portable game console comes with a 1.3-inch display (Crowdfunding)

microByte ESP32-portable-game console 1.3-inch display

We’ve previously seen programmable, portable game consoles powered by Espressif Systems ESP32 processor with the likes of ODROID-GO or WiFiBoy32 both equipped with a 2.4-inch display, and design to play retro games or create IoT projects with a small display thanks to I/O headers. But if for some reason, you’d like an even more compact ESP32 portable game console based on the WiFi & Bluetooth SoC, Byte-Mix Labs microByte may be what you are looking for thanks to a tiny 1.3-inch square display. microByte specifications: Wireless module – ESP32-WROVER-E module with ESP32 dual-core processor @ 240 MHz, 8 MB PSRAM, 16 MB flash, and integrated Wi-Fi and Bluetooth antenna Storage – MIcroSD card slot Display – 1.3-inch ST7789 IPS Screen with 240 x 240 pixel resolution, 60 Hz max refresh frequency Audio – On-board speaker powered by a MAX98357AETE+T I2S amplifier Controls – 13x onboard buttons with 8x Inductive direction […]

Agromon smart agriculture wireless transmitter connects ModBus RS485 sensors to WiFi, LoRaWAN, Sigfox, or NB-IoT

The Internet of Things has many applications including smart agriculture . A few months ago, I talked to a local shrimp farm owner who used Arduino and ESP8266 boards to monitor water and activate pumps only when needed to get shrimps healthy and save on his electricity bill. He built his own solutions, but there are also companies offering easy-to-use smart farming solutions such as Malaysia-based Wondernica’s Agromon “interface wireless transmitter” designed specifically for smart agriculture applications. Agromon has two variants with support for 2 sensors (WR-AGRO-2S) or 3 sensors (WR-AGRO-3S) that share the following specifications: Connectivity – WiFi, Sigfox (RCZ 2/4), LoRaWAN, NB-IoT Sensor Interface – Modbus RS485 (analog input / 4-20mA / 12V-14V output) Power Supply – 12V DC (tolerance up to 14V); supports batteries, solar power, or power adapter Power Consumption – Sleep Mode: 3 mW Dimensions – 130 x 90 x 40mm Ingress Protection – IP67 […]

Mini replica of DEC PDP-11 computer runs 2.11 BSD UNIX on ESP32 SoC

The relatively popular Digital Equipment Corporation (DEC) PDP-11 16-bit minicomputers started selling in the 70s, and were still available in the earlier 90s. While being stuck in Europe due to COVID-19 restrictions, Jeroen Domburg (aka Sprite_tm) decided to design a tiny replica of a DEC VT102 PDP-11 terminal based on ESP32 wireless SoC and running 2.11 BSD UNIX through SimH PDP11 emulator. Jeroen had to do significant work to make SimH works on ESP32 however, with notably the need to optimize the memory footprint: Obviously, ‘just port SIMH to an ESP32’ is a bit of a understatement for the effort that was needed. Even while SIMH is a pretty nice program when it comes to not using any unique APIs, it still is a system developed for a full-blown workstation and assumes RAM is cheap and plentiful. In order to get it running on an ESP32 and still have some […]

MicroMod modular ecosystem offers M.2 microcontrollers cards and carrier boards

MicroMod is a modular interface ecosystem for quick embedded development and prototyping. MicroMod comes with two components, that is a microcontroller “processor board” and a carrier board. PC industry’s M.2 connector is the interface between these two components. The carrier boards are for the usage of various peripherals and the processor board act as the brain of the application system. MicroMod processor board has a dimension of 22×22 mm that can be easily fitted on the carrier boards. Although, the original M.2 standard was dedicated to swapping out peripherals where a user could swap one component with the other one. The MicroMod standard is for swapping out microcontrollers according to the functional and application requirements. MicroMod Processor Boards Artemis Processor Board comes with an Ambiq Apollo 3 Blue Arm Cortex-M4F with BLE 5.0 running up to 96MHz and a power rating of less than 5mW. It also supports the TensorFlow […]

ClusBerry 9500-CM4 – A Raspberry Pi CM4 cluster, industrial style

ClusBerry Industrial Raspberry Pi CM4 Cluster

Raspberry Pi cluster boards / solutions pop-up from time to time. But so far, I think we’ve seen only one based on Raspberry Pi CM4 modules with the upcoming Turing Pi 2 mini-ITX cluster board supporting four of those. TECHBASE has now unveiled a different kind of Raspberry Pi CM4 cluster with ClusBerry 9500-CM4 integrating up to eight Raspberry Pi Computer Module 4 in a DIN-Rail housing for industrial applications. ClusBerry 9500-CM4 is designed to be customizable with a choice of Raspberry Pi CM4 based modules and I/O cards: Standard 9500-CM4 cluster module with Compute Module 4 and a selection of configuration that include: I/O Controller with DI, DO, AI, 1-Wire, RS-232/485 and CAN interfaces Communication Gateway with up to 2x Ethernet, serial ports, wireless connectivity: LTE-cat.M1, 4G, 5G, LoRa, ZigBee, Z-Wave, Wireless M-Bus AI Gateway with Coral Edge TPU via PCIe M.2, or up to 4x Coral Edge TPU […]

Inkplate 10 ESP32 e-Paper display offers faster refresh rates (Crowdfunding)

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. The company says backers were “happy about the versatility and simplicity of the display” but wished for a larger display, a faster refresh rate, and extra features. This gave birth to an upgraded version: Inkplate 10. The new ESP32 wireless display comes with a recycled 9.7-inch display with 1200 x 825 resolution, up to 38% faster refresh rates, as well as extra GPIO pins, an RTC clock, a USB Type-C port, and lower power consumption.

Maypole MicroSD card reader comes with ESP32 for WiFi, smart storage (Crowdfunding)

Several years ago, we covered Zsun WiFi card reader a tiny USB card reader with WiFi and a battery that allowed users to access files via USB or WiFi from any device. People managed to hack the device and run OpenWrt on the little MicroSD card reader, but this required either to open the hardware and do some soldering, or use another method that could potentially brick the hardware, so not an ideal solution. But now Akshar Vastarpara has come with a similar device. Maypole is an open-source hardware MicroSD card reader powered by Espressif ESP32 processor providing both WiFi and the resources for smarter storage. It comes with an optional battery too to access files even without having to connect it to a USB port. Maypole hardware specifications: Storage – Swappable MicroSD cards up to 32GB Wireless Connectivity WiFi 2.4 GHz WiFi 4 via ESP32 WiSoC, Up to 4 […]
