The project presented here provides an isolated interface between the RS-232 cable network and the connected UART systems to protect against voltage spikes and ground loops within the noisy environment and improve system reliability. The project achieves a robust data communication link...

UARTs for AVR MCUs by Nerd Ralph, he writes: I’ve written a few software UARTs for AVR MCUs. All of them have bit-banged the output, using cycle-counted assembler busy loops to time the output of each bit. The code requires interrupts to be disabled to ensure accurate timing between...

The Cricket ONE is the first in a series of small microcontroller boards using the familiar form factor of the Raspberry Pi Zero series of single-board computers. Featuring an ATMEGA328PB and CH340C USB to UART converter, this board is Arduino IDE compatible and includes all of the...

The new Dily3217 is a breadboard friendly Arduino compatible development board that is easy to integrate with more or less the same functionality as the Nano. Powered by a very small Atmel AVR chip, the Dily3217 copies virtually all the features of the already compact Arduino Nano into...

SEGGER announces the release of SystemView V3.10, a major update to its system verification tool for embedded systems. The most significant enhancement is the addition of real-time data acquisition via UART or TCP/IP. Any system with UART or TCP/IP connection, typically Ethernet, can...

If you have used some form of hardware especially those legacy ones or something like the Arduino and other embedded systems you must have come across the term Serial Port, FTDI chip, USB to Serial, or RS232 at some point. So what are those? Well, they mean the same thing - Serial...

This is a 10x10mm USB-Uart converter with 2Mbps interface speed based on the cheap CN330. Source files available on GitHub. CH330(N) works with CH340/CH341 driver as pointed out by Icenowy Zheng who made a small USB to TTL debug board based on the chip to practice PCB drawing with...

Recently the hobbyist market has seen the appearance of the Air602 low-cost ARM WiFi module. This module might be a potential competitor of ESP8266, another low-cost powerful WiFi module, that took the electronics hobbyists by storm long ago and is still extremely popular. But what's...
