FP01 REFERENCE MAIN BOARD / DIMX4 REV 3.1
4-circuit phase dimming
Reference board DIMX4
DIMX4 is a 4-circuit phase dimming reference board that carries SAIence's common control board FP01. Following commands received over RS485, FP01's PSoC 4 drives the power semiconductors on DIMX4 to dim phase-dimmable loads directly.

01 — HOW IT WORKS
SAIence sells FP01
The customer designs the main board
SAIence sells the common control board FP01 and the software that runs on it. DIMX4 is a reference board verified in combination with FP01. After confirming operation with the evaluation test board, the customer builds the production main board to suit the application and enclosure.
DIMX4 test board
- For verification and evaluation in combination with FP01
- Verify on real hardware from RS485 commands to 4-circuit phase dimming output
- Not sold as a production product
Main board
- Design and manufacture your own main board with DIMX4 as a reference
- Change the power supply, output circuits and connectors to suit the application
- Mount FP01 to complete a lighting control module
NOTEThis page presents DIMX4 as one example of a main board used with FP01. For FP01 itself, see the FP01 product page →.
02 — SYSTEM
Signal flow from FP01
FP01 handles communication and processing; DIMX4 carries the power supply, RS485 driver and dimming output circuits. With this division of roles, replacing only the main board extends the system to IGBT dimming or relay control.
RS485
Receives 12-byte commands from the higher-level controller. The driver IC is mounted on DIMX4.
DIMX4UART→
Arduino UNO R4 compatible
The RA4M1 on FP01 interprets commands and manages addresses, groups and dimming levels.
FP01I²C→
PSoC 4
On instruction from the RA4M1, controls the firing timing of the power semiconductors for 4 circuits in real time.
FP01DRIVE→
Phase dimming ×4
The power semiconductors on DIMX4 phase-control the supply and output to 4 dimming load circuits.
DIMX403 — 4CH DIMMING
4 independent channels (0.1% steps)
Dimming levels are specified as logical values 0–1000 (0.0–100.0%). DIMX4 has 4 local addresses and can be controlled per channel or per group. Try the behavior with the sliders below.
* Display is for illustration. See the specification table for supported loads and ratings.

Main boards for FP01
The FP01 firmware identifies the main board by its module type ID and switches the number of local addresses and the control method. DIMX4 is type ID 2. For every type, the customer builds the main board; SAIence provides reference boards verified in combination with FP01 for evaluation.
