Power is supplied by a Diodes Incorporated's AP2112K-3.3TRG1 regulator. #referenceDesign #edge-computing #edgeComputing #stm #relay #sensors #reference-design

The Texas Instruments MSP430FR604x and MSP430FR603x family comprises highly integrated ultrasonic sensing and measurement system-on-chips (SoCs) designed specifically for water and heat metering applications. The featured components, including MSP430FR6047, MSP430FR60471, MSP430FR6045, MSP430FR6037, MSP430FR60371, and MSP430FR6035, deliver best-in-class ultrasonic water flow measurement with ultra-low power consumption. These microcontrollers excel with an active mode current consumption of approximately 120 µA/MHz and a standby mode power draw as low as 450 nA with a real-time clock (RTC) enabled. Key functionalities include a high-precision differential time-of-flight (dTOF) accuracy of less than 25 ps, integrated analog front-end, programmable pulse generation (PPG), and an analog comparator. They also interface directly with standard ultrasonic sensors up to 2.5 MHz and feature up to 256KB FRAM, robust RAM options, and integrated LCD drivers for up to 264 segments. The embedded low-energy accelerator (LEA) enhances digital signal processing capabilities, making these components ideal for battery-powered metering solutions. Peripherals include multiple enhanced serial communication interfaces, high-performance ADCs, DMA controllers, and a suite of timers and encryption modules. These features combine to offer a powerful solution for high-accuracy, low-cost, and ultra-low-power metering applications.

The LIS3DH is a very popular low power triple-axis accelerometer. It's low-cost, but has just about every 'extra' you'd want in an accelerometer. This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus

An ATtiny13 is more than sufficient to control almost any number of NeoPixels via an IR remote. The NeoController was originally developed as a tester for 800kHz NeoPixel strips. Since there was still so much flash left in the ATtiny13, an IR receiver was integrated so that some parameters can be controlled with an IR remote control. In this way, it is also suitable as a simple and cheap remote-controlled control unit for NeoPixels. Due to its small size (21.6mm x 11.4mm), it can be soldered directly to the LED strip without any problems. The power supply via a USB-C connection enables currents of up to 3A. There is still more than a third of the flash memory left for additional ideas.

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 (including LED), a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. 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. #template

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

The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.
