RZR Mini Multiplexer Part 8 – Canbus R&D

RZR Mini Multiplexer Part 8 - Canbus R&D.

Earlier work on checking the CAN-BUS connection and signal on the RZR 1000S. I capture some traffic to ensure I can see at least the speed and gear selection for the new module to control the HCControl2.

RZR Mini Multiplexer Part 7 – Rework and Reuse of Prototype PCBs

RZR Mini Multiplexer Part 7 - Rework and Reuse of Prototype PCBs.

Rework of an early prototype to use with the canbus controller and to have an additional RS485 device on the bus. HCControl2 is in the RZR 1000 S at this point and replaced the relay for the lightbar and winch. I'll be adding reverse and rock lights soon to integrated with CanBus to enable turning on the reverse lights in reverse and auto rock lights on at low speed.

RZR Mini Multiplexing Part 5 – Building PCB’s

RZR Mini Multiplexing Part 5 - Building PCB's by hand with parts on both sides of the board.

In this video I build a prototype of the multiplexer board. Stencil process, placement and reflow of a double sided board with parts on both sides.  PCB stenciling, placement and reflow by hand for the prototype process.

RZR Mini Multiplexing Part 4 – Testing

RZR Mini Multiplexing Part 4

I load the test code onto the development board. The design for the prototype board from OSHPark is verfied. I complete some simple verification of design related to the outputs and light load testing.

RZR Mini Multiplexing Part 3 – STM8 Software

RZR Mini Multiplexing Part 3

This is a multipart series of design, prototype and build of a small multiplexing system for UTV's. Initially this will replace lighting and winch relays with solid state control. In this part 3, I go over the base software using OSX with the STM8.

RZR Mini Multiplexing Part 2 – Testing with STM8 Discovery.

RZR Mini Multiplexing Part 2 - Testing with the STM8 Discovery Board

I explain using OSHStencil to prototype a board with double sided parts. I also discuss high side switching with a MCU. The first testing happens with two development boards from STMicro using a STM8 Discovery board.

RZR Mini Multiplexing Part 1 – A Smart Solid State Relay for Lightbar, Winch, and anything else on a UTV.

RZR Mini Multiplexing Part 1. This is a multipart series of design, prototype and build of a small multiplexing system for UTV's. Initially this will replace lighting and winch relays with solid state control. The goal is to replace the traditional use of a relay in the rzr for winch and lighting control. Later I will integrate this with canbus work for speed and gear info from the Polaris RZR to turn on reverse lights based on gear selection and turn on rock lights at low speed.
