The scope of this document is limited to describing requirements for the FJ2500 product
described herein; it describes the functional and technical requirements as required to initiate
development of the product

This document is intended to outline the functional and technical requirements from a general
market and/or customer perspective. It is not intended to be a detailed technical design
specification. Additional design specifications and other technical documentation will be
generated as needed over the course of the development process.

1.3 General Information
The FJ2500 product is designed on proven technology from the M6 & M8 products. This product
shall utilize core electrical design and firmware as the M8, with the addition of mechanical
reconstruction to bring overall product footprint down.

Multiple build variants of the FJ2500 will be supported, these will be:
● FJ2500 with BLE
● FJ2500 with BLE + CAN
● FJ2500 with BLE + RS232/RS485 + CAN

Actual launch of specific SKUs will be based on the following initial priorities:
● SKU #2 - FJ2500 with BLE + RS232/RS485
