RVDR+

Commencing July 2023

This is my fourth PCB project in the making. Just a bunch of ideas that I could think of.

Component to consider:

• CM4 as main CPU
• Utilize PCIe for storage
• U-blox SARA-R5 series for LTE and GNSS connectivity (SIM card or E-SIM?)
• powered with battery, need utilized low-power design (power supply design)
• Camera module for recording purposes
• Various sensors; temperature, motion, proximity, magnetometer
• Display with touch screen capability? (needed further research)

Software:

• Plate recognition (OpenCV and in C++)
• MQTT client

link kept as reference for Electronic Design:

• BMS/Power supply Design for CM4
• PiJuice
• PowerBoost 1000 Charger
• CM4-POE-UPS-BASE
• BQ24160 ACTIVE I2C 1cell 2.5A Buck battery charger with dual-input, Power Path and USB detection
• Raspberry Pi PCIe Devices
• Lecture notes: Battery Management and Control
• SparkFun MicroMod Asset Tracker Carrier Board, Ublox SARA-R5
• RPi CM4 - LiM Carrier Board series

Brekaout board

• High-Efficiency, 28V, 3A, 450kHz, Synchronous Step-Down Converter In SOT583 Package

More info to be added soon

Link for project build reference:

• Flashing the Atmega32A
• Mechanical Keyboard Prototype With V-USB & QMK
• How to burn the Plaid keyboard bootloader using Arduino Nano

The command for the avrdude:

avrdude -c stk500v1 -P COM12 -p m32a -U flash:w:C:/Users/ucems09/qmk_firmware/coseyfannitutti_discipline_default.hex:i -v -b 19200

• -c stk500v1 use stk500 version 1 as the programmer.
• -P COM12 port value, for this it is COM12, can check Arduino IDE.
• -p m32a type of MCU, for this it is m32a for Atmega32A.
• -u flash:w:C:/Users/ucems09/qmk_firmware/coseyfannitutti_discipline_default.hex:i program to be flashed in hex format.
• -v just more information in the CLI.
• -b 19200 set the baudrate this is 19200, was burn by the arduino ISP, very important to set the baudrate.
