EV5920-5048-V-00A Evaluation Board
This is a recreation of the [EV5920-5048-V-00A](https://www.monolithicpower.com/en/ev5920-5048-v-00a.html) from MPS which demonstrates a MP5920 Hot-Swap controller commanding 5 MP5048 e-fuses in parallel.
WIP Items:
-Routing
In flux, this project demonstrates hierarchal design through the use of modules. Additionally, parametric symbols are used extensively to improve schematic cleanliness. Components in the canvas are locked because their positions correspond to the same positions as the original layout.
Changelog from Original MPS Design:
- Not including GPIO2 or GPIO3 as included in the original board due to NC pin name on the IC.
- PC1 and PC2 footprints are 5mm in pitch and 12.5mm in diameter rather than the 16mm diameter in the original layout. This change corresponds with the selected part more accurately.
-Renamed Designators to be More Verbose

Lethal Company Pro Flashlight Power Board V1
Lethal Company Pro Flashlight
Broken Features:
- U2M cannot be line powered from this circuit so the LED driver does not regulate.
[Find the acompanying button board here](https://www.flux.ai/markwuflux/lethal-company-pro-flashlight-button-board)
-Ultra bright
-Makes click noise from speaker
-Wirelessly transmits battery life (maybe use Ubo to receive this)
-Drive a SST-40 Chinese LED
I want this thing to be super bright! The brighter the better, but keep it simple.
These LEDs will draw a lot of power, so we need some sort of CC source. It doesn't have to have high bandwidth.
I am thinking about a DIY microcontroller buck converter with PID duty cycle control.
Mistakes in this V1 design:
- No pullup resistor on PG of Module1

Universal Electronic Derailleur V1
NOTICE: This board has a incorrectly sized battery holder. If building this revision, also build the [adaptor board](flux.ai/markwuflux/adaptor-board-for-universal-electronic-derailleur-v1)
Cable Index Shifting Electronic Derailleur. The first version just uses a linear actuator because I suck at ME design. I imagine it would be pretty easy to build a reeling one with positional feedback.

Adaptor Board for Universal Electronic Derailleur V1
I messed up the battery dimensions on the V1 so here is a CNC-able fix to adapt the original battery to the original PCB.

MP5920 Module
This is a MP5920 module which mirrors the [EV5920-5048-V-00A reference design](https://www.monolithicpower.com/en/ev5920-5048-v-00a.html)
You can utilize this module as many times as you like in your project without having to recreate the layout each time.
