A couple of times a year I send in a bunch of PCBs. As usual I combine multiple designs and have them delivered express. That sounds a bit expensive but when ordering about 4-5 designs the cost is almost the same as the other snailmail options. I also make sure I send...

When I was in China last year I sourced a couple of small E-ink displays (GDEH0124S01) through Taobao. They were simple ones with 8 14 segment characters. After some searching on the Chinese website from the manufacturer I found the datasheet. It was by all means not...

Today came in a new batch of PCBs from DirtyPCB.com, of which one is a new revision of the BlackMagicProbe. This revision is almost the same except it has a polyfuse in its powersupply to the target, a dedicated voltage regulator instead of P-FET, its programming...

Today I stumble across a neat/new feature in Eagle I haven’t seen before. Prolly in there since early versions 7, but at least it is present in version 7.5.0 (current version at writing is 7.7). Some PCB manufacturers will accept panelized PCB and you can save a...

Since I don’t use the DHL shipping option for PCB, it takes quite a while before the boards roll in. Today came in the STM32/GD32F103 QFN32 breakout board. I was very excited (for weeks) and soldered all the components quickly on the board. Uptill now I used...

Prolly not, but I haven’t made a developmentboard before and I didn’t know of a development board that uses the QFN36 footprint. I recently went on a trip to Shenzhen to visit Ian from Dangerousprototypes.com and there I learned about a big Chinese...
