https://www.electronics-lab.com/ch340e-new-small-serial-usb-chip/
WCH, a Chinese integrated circuits manufacturer, has just released a new serial to USB chip called CH340E. Unlike other CH340 chips, it doesn’t require an external crystal and also needs less PCB space and BOM. CH340 is a 3x3mm tiny chip comes in MSOP10 package and has 10 pins. Although it is smaller than other alternatives, it is […]
Using an ATmega328 without a crystal
https://www.electronics-lab.com/using-atmega328-without-crystal/
Here is another guide from David Johnson-Davies @ technoblogy.com explaining how to program an ATmega328 on a breadboard using the Arduino IDE. The guide is focused on how to use the internal clock of the microcontroller and how to achieve this using the Arduino environment. By default Arduino IDE doesn’t include a Boards option for an […]
Programmable Power Supply Using OPA548
https://www.electronics-lab.com/programmable-power-supply-using-opa548/
Project provides 1.2 to 20V DC output with current limiter adjustable to 0-5A. I have tested the circuit with 250mA output without a heat sink. Project is capable to drive 3A continues load and 5A peak, large size heat sink required for full load. The tiny power supply based on low cost OPA548 high-voltage and […]
Bomist – Parts Inventory and BOM Management for Electronics
https://www.electronics-lab.com/bomist-parts-inventory-bom-management-electronics/
It all started a few years ago with Component Organizer, than BOMER and it’s now called BOMIST. The software runs locally, so no server nor setup required and you can have as many databases as you want (just run as many instances of BOMIST as you want). Additionally, it is integrated with Octopart, meaning you […]
Proto Board Power Supply
https://www.electronics-lab.com/proto-board-power-supply/
David Johnson-Davies @ technoblogy.com build a breadboard friendly power supply to power your Arduino or other low power electronics. The power supply is able to deliver 0V to 5.5V at up to 0.5A and it’s powered from two Li-Ion rechargeable batteries. The output can be adjusted using a rotary encoder, and the voltage is displayed on a […]
