Why source displays locally from Communica
Finding the right display module can stall a project - whether you’re a university lab building a prototype, an automation technician integrating an HMI, or a maker assembling a compact IoT device. Communica keeps practical, in-stock display solutions across pixel types and interfaces so you can move from design to test without long overseas lead times.

Range and local availability
We stock character LCDs, monochrome and colour OLEDs, SPI/I2C and parallel TFT modules, e-paper for low-power readouts, plus ready-to-use display shields for Arduino and Raspberry Pi. Popular brands and maker-friendly modules are available across our catalog - browse product groups under Collections or see our full index on All Products. Branch pickup in Samrand, Pretoria and Cape Town reduces wait time compared with import-only suppliers.
Specification callouts - what to check first
Before you order, confirm three quick specs: interface (SPI, I2C, 8/16-bit parallel), supply voltage and pixel format (characters, 128x64, 240x320, etc.). These dictate required controllers, wiring and driver code. Use the Compare Specs option to match modules by those parameters.
| Type | Typical interface | Best for |
|---|---|---|
| Character LCD (16x2, 20x4) | I2C/parallel | Simple menus, low-cost displays |
| OLED (128x64) | I2C/SPI | High contrast, small panels |
| TFT (240x320, 480x320) | SPI/parallel | Graphical UIs, images |
| E-paper | SPI | Static readouts, battery-powered |
Compatibility guidance and accessories
Most microcontrollers and single-board computers can drive common modules, but confirm voltage levels (3.3V vs 5V). Use level shifters or choose 3.3V-ready modules for Raspberry Pi. Essential accessories: mounting bezels, ribbon cables, display backpacks (I2C converters), and touch overlays. We bundle popular pairings - for example, 2.8" SPI TFT + touch panel + 4-wire cable - to avoid mismatch delays.
Quick wiring example (SPI 4-wire)
Typical 4-wire SPI connections between a microcontroller and TFT:
MOSI ----> SDA / MOSIMISO ----> (often unused)SCLK ----> SCL / SCKCS ----> CSDC ----> D/CRST ----> RESETVCC ----> 3.3VGND ----> GND
If your display requires 5V power but logic is 3.3V, add a logic-level shifter on the signal lines. For student labs, choose modules with onboard regulators and level translation to reduce classroom troubleshooting.
