VoCore is a small Linux computer with Wifi that can work as a full functional router. It runs OpenWrt on top of Linux. It contains 32MB SDRAM, 8MB SPI Flash and uses RT5350 (360 MHz MIPS) as its heart. It provides many interfaces such as 10/100M Ethernet, USB, UART, I2C, I2S, PCM, JTAG and over […]

ESP8266 16MB Flash Handling


https://www.electronics-lab.com/esp8266-16mb-flash-handling/

Piers Finlayson shares his adventures in programming the ESP8266 to access 16MB flash: To put this in context, the original ESP8266 modules (such as the ESP-01) offered 512KB of flash, with the more recent ones (ESP-07) 1MB and then 4MB. The maximum addressable flash memory of the ESP8266 is 16MB according to the datasheet. (The […]

The potential competitor of ESP8266 wifi module will be available next week for just $2! Pine64, the manufacturer of the first $15 64-bit single board computer, is now preparing to launch “PADI IoT Stamp” RTL8710AF module. This module has the size of the stamp, a small 24mm x 16mm package with powerful specifications compared to […]

ESP8266 Wifi enabled 8×64 pixel LED matrix display


https://www.electronics-lab.com/esp8266-wifi-enabled-8x64-pixel-led-matrix-display/

Raj @ embedded-lab.com build an ESP8266 based led matrix display. This matrix is a modification of his previous bluetooth version and uses an ESP8266 as a web server to setup the display message. No other microcontroller is used to control the display so things are kept simple and easy to build your own. This project […]

4Duino – A 2.4″ TFT LCD IoT Display Module


https://www.electronics-lab.com/4duino-2-4-tft-lcd-iot-display-module/

If your application needs a controller with display interface and a network connectivity, then you need to think about using 4Duino from 4D Systems, a 2.4″ TFT LCD IoT display module. 4Duino key features 4Duino has ATmega32U4, a 8-bit MCU from Atmel, which is the same microcontroller inside Arduino Leonardo. 4Duino also preserves Arduino UNO […]

RFM69 WIFI Gateway


https://www.electronics-lab.com/rfm69-wifi-gateway/

The RFM69GW is a RFM69 to MQTT gateway that uses the ubiquitous ESP8266 chip. There are two or three similar projects that I’m aware of but I’ve put together some hardware and firmware features that make it different. by Xose Pérez: I’m using Felix Rusu’s RFM69_ATC library so it supports Monteino nodes with Auto Transmission […]

ESPUSB – An USB Software Stack For ESP8266


https://www.electronics-lab.com/espusb-usb-software-stack-esp8266/

ESP8266EX and even the new ESP32 SoC lack a USB hardware transceiver, so [CNLohr] decided to develop a USB software stack for ESP8266. After a quick search, I think it is the first try to do a USB software stack for esp8266. USB software stack is a firmware-only implementation of a USB. ESPUSB works in […]
