Electronic blocks
A question, a problem or a suggestion, don't hesitate : a little email
In this page, you will find some electronics blocks build sufficiently modular to be used in different applications. For this, I assume some developing constraints:
- PCB sizes (2 x 2 inches, 2 x 4 inches, 4 x 4 inches and 4 x 6 inches) wherever possible (in older applications I was using 100 x 160 mm boards),
- Standard connectors both from physical and protocol point of view (for example HE20 connector and 8 bits bus for microcontroller based applications).
Breadboard
A PCB merging the different standard PCB cards I use.
Useful for a trial circuit or for a single copy one.

A set of adapters to easily mount integrated circuits or to plug them on a labdeck.
A first processor board with:
- 8031 (or 40 pins compatible controller),
- 8 à 32 ko of EPROM + 8 à 32 ko of RAM,
- Outputs to LCD display , extension,...
Very useful for software tests. A multipurpose processor board for applications needing RAM.
A second processor board with:
- 8031 (or 40 pins compatible controller),
- 8 à 32 ko of EPROM,
- Extension, reset, I2C bus, RS232,...
A basic board (no RAM) dedicated to small propjets.
A keyboard with:
- 16 keys,
- 6 leds.
(To be used with libcla1.zip library).
A combined display and keyboard board with:
- 6 keys,
- An LCD 2*16 characters (or compatible).
(To be used with libcla2.zip library for the keyboard and liblcd.zip library for the display).
A combined display and keyboard board with:
- 6 keys,
- A graphical LCD with 122*32 pixels.
An 8 inputs and 8 outputs TTL interface:
- Outputs in 4 groups (with power supplies) for instance to control 4 stepped motors,
- Inputs with 2 usable as interrupts and all directly connectable to switches.
Board which realizes the interface between a Peri1 bus and an ispLSI1016 FPGA from Lattice.
The board also includes an oscilator for the clock of the ispLSI and a large breadboard zone.
An USB interface using a PIC16C765. Can be used:
- As an USB interface of a more complex project,
- As a stand alone card (for USB->RS232 conversion or tests for instance),
- As a programmation support board.
An expantion board allowing to connect 4 boards on the same Peri1 bus.
An unipolar stepper motor interface (with 5 or 6 wires) with 2 end-of-course switches.
