The "Green Dot 2040E5" Board is a Node that interfaces RS485 Sensor probes and can log information to the cloud using LoRa Connectivity. It uses the XIAO RP2040 and the LoRa-E5 (STM32WLE5JC) modules from Seeed Studio to do its magic. It also has amazing power management capabilities (Solar charging, Battery protection, etc) that make it very useful for IoT applications #internetOfThings

Guitar pedal starter template based on project by Mark Wu. Includes schematic and PCB layout for basic DIY pedal hardware. This includes two 1/4" jacks (one for input and one for output), a 9V power supply, a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit.
size is a good default size for a 125B enclosure.
The headers are meant to be unpopulated so that wires can be soldered to the pads.
PCB design rules imported from the JLCPCB 2-layer stackup template.
Meant to be used with the 3PDT Breakout Board on my profile.

This bee hotel version is an intermediary version that implements some featuresets. The main feature that we are leaving out is Matter support over Zigbee (for a wider range in the backyard).
In this version, we are implmenting:
-Legacy WiFi/BT connectivity.
-Camera with flash capability
-Solar Charging
-Energy Storage
-Humidity and Temp Sensor

I wanted to create a business card that has some functionality and shows off a bit of my portfolio IRL:
-NFC to my flux page -here's the [instructables](https://www.instructables.com/PCB-Business-Card-With-NFC-Make-Yours-With-NFC-QR-/)
-Put a bunch of modules on it

Template for Arduino Uno R3 Shield. Include an official pinout so you will always know Arduino names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Arduino Uno R3 itself along with the board outline on the silkscreen.

I want to create a standard interface from my PCBs to my test equipment. My equipment:
PSU: Rigol DP832
Scope: Siglent SDS 1202X-E
WaveGen: Siglent SDG810
Logic Analyzer: DSLogic Plus 400MHz
VNA: NanoVNA V2
6 scope channels (4 1X, 2 10X)
8 Logic Analyzer channels
1 Wavegen channel
4 Power Nets ( 2 pins each) (tie power nets to oscilloscope inputs)

A buck boost converter that can be powered from a Li-Ion battery and output 3.3V @ 500mA. Powered by the TPS63051YFFR and in the same package as a standard Adafruit buck converter.
Expect to squeeze around 5-10% SoC from a typical Li-Ion battery.
Input Voltage Range: 2.5V to 5.5V
