If you haven’t seen the first part, here it is: https://youtu.be/YYE7vHrqCd8 This time around we mainly talk about connecting the #eps to the side panels (where the solar cells are) and to the rest of the system. Also, I will tell you about how I plan to make the battery chargers and buck voltage regulators easy to tinker with and swap out. *Dev kit shop will be up in late 2025 / early 26* – get pinged: https://forms.gle/5a2UZdfcyUmFjTZd8 ## 🛰️ Support This Project If you are looking for a way to support this channel, leave a tip or become a member :) - Channel Memberships: https://www.youtube.com/channel/UCLf9aKlW-TbC8zbrl0OvKLQ/join - Patreon: https://patreon.com/buildacubesat - Ko-fi: https://ko-fi.com/buildacubesat - PayPal: https://tinyurl.com/bac-paypal-donation *Timestamps* 00:00 Intro 00:17 Side Panel Connectors 04:46 PCB Stacking Connectors ("MacroMod") 08:24 I2C GPIO Expanders 09:37 Test Points, Fiducials, Misc. 12:03 Battery Charger and Voltage Regulator Modularity 13:28 Compatible @pololu Parts 14:06 Module Footprints 18:00 @analogdevicesinc LTM8062 Battery Charger Module 25:34 @analogdevicesinc LTM4675 Voltage Regulator Module 30:44 ERC 31:15 Outro *Repo Links* EPS v1: https://codeberg.org/buildacubesat-project/bac-hardware/src/branch/main/eps MacroMod Pinout v2: https://codeberg.org/buildacubesat-project/bac-hardware/src/branch/main/eps/MacroMod-Pinout-v2r1.pdf *Video Links* EPS Schematic Part 1: https://youtu.be/YYE7vHrqCd8 Block Diagram and Part selection: https://youtu.be/0nqGzLot9TQ Battery Selection: https://www.youtube.com/watch?v=01msKY_211g M.2 Connectors (aka.
