For Sale: Microcontroller Board [US]
« on: May 13, 2024, 07:04:07 pm »
For Sale:
Small PC board with microcontroller, peripherals, and digital I/O.

This is my model "AVT-822".
I developed it special for a customer.  (That customer later disappeared.)

Small board:  3.0 x 4.0 inches
Motorola/Freescale/NXP  MC9S12DG128CPVE microcontroller.
 - Motorola BDM connector.
 - one channel of CAN (J1939 compatible).
 - one channel of RS-485 (J1708 compatible).
 - one '82C54' programmable interval timer (frequency generator).
 - two buffered frequency outputs.
 - two buffered digital outputs.
 - four buffered digital inputs (Schmitt trigger inverter).
 - one UART channel connected to a debug header.
 - wide range power input to a 5v linear regulator.
What can you do with this board ?? !

Picture of the board is attached.
Picture of the board with debug adapter is attached.
Pictures of the top silkscreen are attached.

Direct link to the schematic:

I can provide (on request only) a schematic of the debug adapter.
(I should have one somewhere.)  (UART <--> RS232)

I can provide (on request only) a copy of the last released code I developed for the board.
The code was developed to control a stationary diesel engine via the J1939 CAN bus.
(My code uses the same framework as all my other products.  Hence, it supports external commands and responses through the debug connector.)

At present, I have about qty. 190 boards available.

I'm asking US$ 12. per board (plus shipping).
Offers considered.

I will offer a 20% discount if you buy 5 or more.
If someone buys the whole lot - I'm sure we can come to a suitable agreement on price.

Contact me by email:  MRILEY .at. AVT-HQ.COM
or by Private Message.
I will respond as quickly as I can.

Let me know if you have any questions.
Thank you for looking.
