완료 착불

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.
