Redesign Existing PCB of a product prototype.
Budget: $750 – $1,500 USD
We developed a prototype of our product but now we need a new pcb with necessary improvements and make it ready to send to a Contractor Manufacturer for production.
we have 2 pcb shields, one collects the data and then send it via lora to the gateway (second shield, much simpler)
Our product is a weighing scale to monitor cattle.
Overview of the complexity of the project:
weighing scale board
Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), FLASH 8MB (64M-bits) SPI FLASH , RAM 520KB internal SRAM, with LoRa node chip SX1276
TTL RS232 Converter
Analog to digital converter
RTC DS130
SD CARD
Power Source: Solar panel/battery
Gateway Board
Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), FLASH 8MB (64M-bits) SPI FLASH , RAM 520KB internal SRAM, with LoRa node chip SX1276
SD CARD
Power Source: Standard wall plug socket;
If you can contribute with not only the pcb's design, but helps us to format everything needed to send to a CM in order to start production... you are welcome.
