Immediate access to the parts you need
When you need breakout boards, Arduino shields, sensor modules or communication boards for a classroom build or production run, delays waste time and budget. Communica holds thousands of development and maker components so you can get a fast, accurate quote and move from design to test quickly. Whether you're a student wiring your first sensor, a technician building a proof-of-concept, or a procurement team assembling parts for an OEM pilot, our local stock and branch pickup options reduce lead time risk.
Why request a quote from Communica?
- Transparent availability and lead-time guidance for South Africa
- VAT invoices and account quoting for education and corporate buyers
- Accessory bundles and alternatives suggested to keep projects moving
Common modules we quote
We provide single-line quotes for popular items that students and engineers use every day: Wi-Fi and LoRa modules, I2C and SPI sensor breakout boards, motor driver shields, level-shifting modules, GPS units and power management boards. Explore categories and check stock to see live availability on our site: Shop by category.
Specification callouts we include in quotes
A good quote goes beyond price. Expect clear notes on pinouts, voltage domains (3.3V vs 5V), required level shifting, physical dimensions and recommended headers or sockets. This prevents surprises when you integrate a module onto a board or shield.
Quick compatibility checklist
- MCU voltage: 3.3V or 5V - confirm before ordering
- Interface: I2C, SPI, UART, PWM or analogue
- Driver availability: libraries for Arduino, Raspberry Pi, or plain C/C++
- Physical fit: shield stacking or breakout spacing for breadboards
Sample spec comparison
| Module | Interface | Voltage | Typical use |
|---|---|---|---|
| ESP32 Dev Board | UART / Wi-Fi / BLE | 3.3V | IoT gateways, Wi-Fi sensors |
| MPU-6050 IMU Breakout | I2C | 3.3V / 5V tolerant | Motion sensing, robotics |
| DRV8833 Motor Driver | PWM / GPIO | 2.7-10.8V | Small DC motors, differential drives |
Practical wiring example
Here is a simple ASCII wiring diagram showing an I2C sensor breakout connected to a 3.3V MCU (SDA/SCL pull-ups required if not onboard):
MCU (3.3V) SENSOR BREAKOUT 3.3V ---------- VCC GND ---------- GND SDA ---------- SDA SCL ---------- SCL
If your breakout is 5V only, the quote will include recommended level shifters or alternate 3.3V-compatible modules. For a quick stock check at our head office, use: Branches & Trading Hours to arrange collection from Samrand or Pretoria.
