Immediate availability for time-sensitive projects
When a prototype deadline or lab practical looms, waiting weeks for parts isn't an option. Communica keeps a pragmatic selection of hearing and vision modules, microphones, cameras, DSP boards and testing accessories in local branches so you can collect the same day from Samrand, Pretoria CBD or Cape Town - or request a quotation for larger orders. That local availability reduces project risk, speeds iterations and keeps student timetables on track.
What in-stock looks like
We maintain stocked lines from widely used maker and engineering brands (for example Adafruit-style development modules and established connector and sensor brands) alongside common consumables such as breakout boards, ribbon cables and test mics. For an overview of categories and to browse what's available, see our Shop by Category and the full All Products index.
Quick specification callouts that save time
Before you order, check these non-negotiables: supply voltage and current, interface (I2C/SPI/USB/UART), sample rate for audio/IMU sensors, and camera resolution/frame-rate for vision modules. We list these in product pages, and our branches can advise substitution options when a specific SKU is out of stock.
Head-to-head spec comparison
Use this quick table to compare two common module classes - a low-cost MEMS microphone front-end and a small camera module used in vision prototypes.
| Spec | MEMS Microphone Module | Camera Module (CSI/USB) |
|---|---|---|
| Typical supply | 1.8-3.3V | 5V (USB) / 3.3V (CSI) |
| Interface | I2S/I2C | USB / CSI (MIPI) |
| Key metric | SNR 61 dB typical | 720p @30fps / 1080p @15fps |
| Common use | Audio capture, beamforming | Object detection, local vision |
Compatibility & accessory guidance
Modules are commonly paired with microcontrollers or single-board computers. For instance, a MEMS microphone with I2S output pairs cleanly with an ESP32 or a Raspberry Pi sound card. If you need accessories like breakout PCBs, FFC cables or pre-crimped leads, browse brands on our Shop by Brand page to find compatible parts quickly. Our in-branch teams can confirm pinouts to prevent costly mistakes.
