General Provisions

AZ series controllers may be assembled independently according to the specifications provided and manufactured for personal and non-commercial use only. All other uses (modification, etc.) are prohibited.

Restrictions

When ordering printed circuit boards, you can use any color of the board mask - except red.

I do not provide consultations on assembly/adjustment, since a correctly assembled product from serviceable components does not need adjustment or configuration.

Replacing component ratings is not allowed and may cause the assembled device to malfunction. Let me remind you - modification is prohibited.

Assembly recommendations

For self-assembly you will need (highly recommended) the following components and tools:

Soldering iron or soldering station with temperature control, as well as the necessary power for good heating of contacts. The minimum recommended soldering iron is PX-988

Of course, you will need rosin as a flux (rosin dissolved in alcohol is recommended) and high-quality solder is recommended. Using other fluxes is not recommended.

When soldering small components, it is strongly recommended to use a real optical stereo microscope, the use of monocular or digital microscopes is not recommended, you simply will not notice many defects and time will be lost looking for them.

For installing SMD components, it is recommended to use self-clamping jewelry tweezers

When assembling, it is recommended to observe standard static electricity protection measures.

It is allowed to replace SMD components with smaller ones, but in compliance with the nominal value. It is recommended to use capacitors with an operating voltage of at least 10 V.

After assembly, the printed circuit board must be cleaned of flux; an ultrasonic bath with ethyl alcohol is recommended for cleaning.

Classic AZ controllers

Classic AZ controllers include controllers with one STM32F407VET6 microcontroller without RAM. The main difference is that all controllers have a single firmware and are fully compatible software-wise.

AZ MPI

At the moment, 3 modifications of controllers for the MPI bus have been released (analogous to QBUS, but has different sizes of connectors and the printed circuit board itself)

V1.00

This is the first version of AZ controllers, released in a limited edition in 2019.

V1.02

This is an improved version, available for self-assembly. It uses large SMD components, quite easy to assemble yourself.

AZ v1.01 controller assembly for MPI

V2.00

This is the most "modern" version of the AZ controller for the MPI bus. Here, GALs and BH1s are replaced with EPM240s.

AZ QBUS

For the QBUS bus, only one modification of the AZ controller has been released at the moment.

V1.02

This modification corresponds to modification 1.01 for MPI. It does not contain any other fundamental differences.

AZ v1.02 controller assembly for QBUS

AZ UKNC

Several modifications of the controller have been released for UKNC. The AZ UKNC series controllers are installed instead of the network adapter in the network adapter compartment. The UKNC series computers have two main modifications - different connectors for connecting the network adapter - IDC 2x20 and a blade connector on the printed circuit board.

V1.00

This version is designedintended for UKNC with IDC socket for connecting network adapter. Released in limited quantity.

V1.01

This version is available for self-assembly. It is intended for UKNC with IDC connector.

V1.02

This version is available for self-assembly. It is intended for UKNC with a wide blade connector.

V2.00

An experimental version of the controller, is an analogue of version V2 for MPI. In this version it was planned to implement autoloading of UKNC with AZ, however, due to severe time constraints, the work was suspended.

Advanced AZ Controllers

Extended AZ controllers include controllers with an STM32F407VET6 microcontroller, as well as an FPGA, RAM and sound subsystem.

AZБК

This controller is a kind of combine, as it contains slightly modified microcontroller firmware.

V1.00 Consists of 2 boards

This version is available for self-assembly.
