World's first live soldering stream of a #LoRaWAN device
summary
Claims a world's first live soldering stream building a double-sided four‑layer #LoRaWAN node end to end over eight hours, using stencil + solder paste, reflow oven, hot air and basic bench tools. It places ~80 SMDs including STM32WL, TCXO, secure element and a buck‑boost regulator; measures 1.8 microamps sleep on earlier boards; hits build problems with the regulator and multiple reflows, bypasses the regulator, and ultimately transmits packets with RSSI −55, mostly functional.
