DIY USB to TTL Converter
https://www.electronics-lab.com/diy-usb-to-ttl-converter/
ams31 @ instructables.com show us how to build a DIY USB to TTL Converter using CH340G IC. Lots of USB to TTL modules are available in the market based on various chips like PL2303, FT232, CP2102 and CH340g. I have decided to use CH340g IC. Low costing clones of Arduino UNO & Arduino Nano also […]
Share Your Internet Connection With Raspberry Pi Zero Over USB
https://www.electronics-lab.com/share-internet-connection-raspberry-pi-zero-usb/
Raspberry Pi Zero is the smallest member in Raspberry Pi single-board computers family with a single-core 1 GHz processor chip, a micro-SD card slot, a mini HDMI port and two micro USB ports (one for power, one for USB). A tutorial in CircuitBasics demonstrates how we can get an Internet access for Raspberry Pi Zero […]
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 […]
MemType USB Stick With All Your Passwords
https://www.electronics-lab.com/memtype-usb-stick-passwords/
Noela and Miguel from Area0x33 made a really helpful tool on hackaday.io. They designed a fully open source hardware USB stick to store your username/password pairs on. MemType uses Atmel ATtiny85 MCU and V-USB to do the communication over USB. V-USB is software-only implementation of a low-speed USB device for Atmel’s AVR microcontrollers. Memtype uses […]

Aaron Brady writes: We popped open the case, and there were two main ICs, a Prolific 2303 (the USB to Serial IC) and a ADM3251E (the RS232 line level convertor). I tried to desolder this with no success, but Bas stepped in, cut the leads with a craft knife and ran the iron over the […]
samDEV_09 – Mini devboard for Atmel’s SAMD09 ARM Cortex M0+ Microcontroller
https://www.electronics-lab.com/samdev_09-mini-devboard-atmels-samd09-arm-cortex-m0-microcontroller/
A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and therefore has […]
USB to RS485 converter
https://www.electronics-lab.com/usb-rs485-converter/
Marko Pavlin has published a USB to RS485 converter. He writes: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added […]
Using USB Type-C on hobbyist projects
https://www.electronics-lab.com/using-usb-type-c-hobyist-projects/
Tyler has build a breakout board for Type-C USB plug and explains how this can be used in various DIY projects. The new Type-C USB connector is the latest addition to the USB connector standards. It offers reversible plugs, direction independent cables, USB3.1 speeds, and 3A charging in a connector only a little bigger than […]
USBuddy: USB development tool
https://www.electronics-lab.com/usbuddy-usb-development-tool/
Jakub has designed and built a USB breakout board with current monitor – USBuddy: Do you sometimes develop with USB? I do. So I need to access data lines, bus voltage and I’d like to easily monitor the current too. I made myself a small companion (43.5 mm × 22.5 mm, 9.5 g) to do […]
