2018 - arduino LoRa and USB adapter for analog DC current clamp
From Dec-2018
IoT LoRa adapter for an analog DC current clamp, turning it into a data sending device. The design works for Gossen Metrawatt (CP30), Picotech (TA189), Rohde&Schwarz (RT-CZ02) or Prosys (CP-30) which are all the same OEM product. An Atmel ATSAMD51 programmed with Circuitpython and an ADS1115 was used for the data akquisition, RFM96W for the LoRa communication. The USB interface was hand soldered from an USB plug/jack and put into a 3D printed housing. PCB: https://aisler.net/p/ANWRGXCV
