It’s Almost A New Raspberry Pi Compute Module 4. But Not Quite

We know that readers are familiar with the global chip shortage and its effects on product availability. The Raspberry Pi folks haven’t escaped its shadow, for even though they’ve manag…

Did You Know That The Raspberry Pi 4 Has More SPI, I2C, UART Ports?

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspb…

How Do You Make A Raspberry Pi On A Stick?

We agree with [magic-blue-smoke] that one of the only things more fun than a standard Raspberry Pi 4 is the Compute Module form factor. If they are not destined to be embedded in a system, these ne…

Raspberry Pi Cameras Stand In For Stereo Microscope

Handling tiny surface mount components and inspecting PCBs is a lot easier with a nice stereo microscope, but because of their cost and bulk, most hobbyists have to do without. At best they might h…
