Paul, If memory serves there is a TriEmbed member with one of the low current characterization devices. Maybe the CurrentRanger? But I cannot recall who that might be. https://lowpowerlab.com/shop/product/152 And here is a roll your own option using an ATTiny85. The Technoblogy is great as well. http://www.technoblogy.com/show?2S67 Another DIY option. https://www.lab4iot.com/2020/07/24/a-low-cost-current-measuring-technique-for-iot-devices-diy/ Best, Shane On Wed, Aug 25, 2021 at 4:56 PM The MacDougals via TriEmbed <[email protected]<mailto:[email protected]>> wrote: I want to measure DC current of ESP8266 while in deep sleep. Should be around 19uA. I recall Dave Jones had a device that turned a volt meter into an amp meter. https://www.eevblog.com/product/ucurrentgold/ I found this clone: https://github.com/nfhw/tinycurrent Looks like it is available assembled from Germany for 60.50 € https://www.n-fuse.co/devices/tinyCurrent-precision-low-Current-Measurement-Shunt-and-Amplifier-Device.html Anyone already have one of these? Anyone else interested in getting or building one?
