At first I was hesitant, but using 70x130mm plastic cable channel turned out great use as an under the desk cable management. It looks neat now.

New red PCB panels just arrived. 😍 Thank you, JLCPCB, for quality service and fast delivery. These are the new series of sensor and buck-boost converter modules for IoT applications by yours truly (MakerTronika Labs). Be sure to follow for more updates. #iotdevices #iotproject

JST-PH 2.00 2Pin connector. LCSC 🆚 Aliexpress versions. Guess which is which.

Digging the red soldermask on these PCB panels.

Had to do a pinout crossover between a Grove connector & I2C OLED display and it turns out SO8 to DIP8 PCB adapter works great l. After some careful soldering, voila! We have a working demo 🎉

⚡ Doing some low-power measurements with my upcoming #Penguino RAK3172 Feather dev-board. 10 µA sleep current @ 3.7Vin is a not bad at all for a linear-regulator powered board. My trusty Otii Arc helps a lot with this kind of battery emulation measurements. 🔋 #LoRaWAN
