When I was working for ChargePoint, I designed a set of CIBs (CIB – Common Interface Board) for allowing rapid development of test fixtures.

This calculator performs calculations for potential divider circuits, as well as giving you information about the power and current that your potential divider will draw, and the ratio for use in your code if you are using this for working out the voltage…

Since my IPCC Track Width Calculator, I have been thinking about how to make an online alternative to Under Pressure.

Following on from my two IPC 222119 posts, IPC 2221 standard trace widths and the one where I normalised them for KiCad Traces Net classes, I have built an online calculator that you can use to work out the required track width with different parameters.

The ATtiny 1614 is an 8-Bit microcontroller available in a SOIC-16 form factor.

To build a Unified Program and Debug Interface (UPDI) programmer20, I started with a USB-2TTL “USB to TTL Serial Communication Conversion Module” from eBay.

CXA1304-0000-000N00B440F LED size I have done the following work on Net classes in KiCad, which is derived from what I wrote about IPC 2221 standard trace widths and Creepage and Clearance a while ago.

When designing boards, one of the things I spend a lot of time checking is if my UART transmit (TX) and receive (RX) lines are the right way round, or switched over.

A while ago, I wrote a post about choosing the resistor values for setting ADDR on the MCP23018.

Over on Reddit, there is a post called “Client complaining about our own branding on our own custom products, how do you handle white labelling?
