Arduino Compatible Expansion Board for Onion Omega
The Breadboard Dock brings breadboard compatibility to the Omega! Power the Dock and your Omega with any Micro USB cable and plug it directly into a standard breadboard. The Omega’s pins are mapped 1-to-1 onto the breadboard, allowing you to access all of the Omega’s I/Os in your breadboard project.
The Omega ADC Expansion will bring a new world – the analog world – directly to your Omega2 projects. Based on the ADS1115 analog-to-digital converter chip, this Expansion provides 4 analog input channels, each with 16 bits of precision at a maximum of 860 samples per second, and communicates with your Omega using I2C.
Universal Miniature Expansion Board for Onion Omega
Development board based on ATSAMD21G18 ARM Cortex M0 . It can be the basis of many electronic projects and used with other devices such as ethernet or bluetooth sensors or shields can be a good way to automate your home.
This board is just like the BeagleBone Black but small enough to fit in your wallet.
This development board is based on the 32-bit ARM processor, compatible with Maple Mini. It is programmed with Maple IDE, a development environment very similar to Arduino IDE, even though the architectures are completely different.
SparkFun Pro nRF52840 Mini - Bluetooth Development Board
METRO Mini is the culmination of years of playing with AVRs: we wanted to make a tiny, breadboard-friendly development board that is easy to use and is hacker friendly. Metro Mini can be programmed with the Arduino IDE.
Espressif's ESP-EYE is a miniature ESP32-based development board that combines a digital microphone, ESP32 (of course) with 8 MB PSRAM and 4 MB flash, and a 2 megapixel camera. There's a few buttons and LEDs as well for basic control and configuration.
Adafruit Feather M0 Express - Designed for CircuitPython (ATSAMD21Cortex M0)
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
Sonoff DEV is a universal low-cost WiFi development board designed by ITEAD.A lot of Sonoff fans keep asking firmware programming questions, now this version is just the module you are looking for.With only one micro USB cable to connect to PC, users can start to develop and design IoT device right away.Sonoff DEV supports to program personal firmware!...
