In this video, I hand-assemble my custom "Bare Bones" ESP32-C3 V2 board from scratch using a stencil, solder paste, and a hot plate. In our previous project, we achieved the "Holy Grail" of 5µA deep sleep, but we relied on a factory to build it. Today, we are doing it the hard way. This V2 design features a unique Dual-Mode Power Topology—a slide switch that allows you to choose between Regulated Mode (safe for 4.2V LiPo/USB) or Direct Mode (regulator bypass for 3.2V LiFePO4), drastically reducing quiescent current. I’ll walk you through the entire process: from the 4-layer KiCad design optimized for RF performance to the "Pinky Anchor" technique for placing small 0805 components with shaky hands. We’ll also cover how to design castellated holes so you can use this board as a module in your own projects. PCBWay provides professional PCB manufacturing, PCB assembly, and rapid prototyping services to help bring your electronics projects to life. I used their service for the PCBs, the electropolished stencil, and even the soldering tools used in this video! *In this video:* *Dual-Power Modes:* How to safely bypass the LDO regulator. *Manual Assembly:* Using the "Under-Tape Wings" method and stencils. *Reflow Soldering:* Cooking PCBs on a heat bed. *Power Profiling:* Testing the deep sleep current with the Nordic Power Profiler II. *Resources & Links:* 📄 *Read the Full Article & BOM:* [https://bj-dehaan-solutions.com.au/ar...] 📂 *Get the KiCad Files & Gerber (GitHub):* [https://github.com/Ben-BJD/ESP32-C3-B...] 🛠️ *Order this Board (PCBWay Shared Project):* [https://www.pcbway.com/project/sharep...] *Related Videos:* 📺 *Previous Episode (The V1 Prototype):* [   • Save Battery Life on Your ESP32 - How to M...  ] ☁️ *IoT Data Logging Tutorial (ThingSpeak Code):* [   • ESP32 WiFi Data Logging Tutorial (No Cloud...  ] 🔋 *Deep Sleep Programming Guide:* [   • Save Battery Life on Your ESP32 – Deep Sle...  ] ⏱️ TIMESTAMPS: 0:00 Can we beat the factory? 0:53 The "Vampire" Problem & V2 Solution 1:59 KiCad Design: 4-Layer Stackup & RF 3:19 Ordering Stencils & Tools 4:30 Paste & Place (The "Pinky Anchor" Hack) 6:06 Reflow Soldering on a Hot Plate 6:57 Smoke Test & Programming without USB 7:41 Power Profiling: Did we hit 5µA? 9:05 Conclusion #ESP32 #PCBDesign #Electronics #IoT #LowPower #PCBWay #KiCad #Soldering
