Probably a Chinese copy. Fine them handy for thing I use a lot. Keep electronics?parts and assemblies in this Harbor Freight rack and a couple?of plastic?multi-drawer?storage units on top.?
I get enough use out of the 881 to have burned out heating coil. Second soldering station, the first went through its transformer. The irons last about a year.
No, that's Dave Schwartz' Smart Hand Control (SHC) for OnStep motor controllers. It' built around an Espressif ESP32 development board. Use it to test the MCU modules before?soldering?them on their PCBs. Hate to waste a $2 PCB. The MCUs are fabbed by Taiwan semi, but the modules are assembled in China. At $3 a unit you have to do your own QC. They run about 10% defective. Mostly in the USB circuit. The SHC runs about $10-12 in parts. I sell them as a kit for $25 assembled for $40. The switches don't travel well thus I mount them for shipping.
