Maker Modules
Arduino, ESP32, Raspberry Pi — dev boards
Dev Board (Arduino / ESP32 / RPi)
Module
A ready-made board with an MCU, power, USB and broken-out pins so you can prototype without designing a circuit board. The fastest way to start building.
FPGA / CPLD Dev Board
Module
A chip whose logic gates you wire up in code: describe hardware in Verilog/VHDL, synthesize, and the FPGA becomes that circuit — running everything in true parallel at nanosecond speed. The VLSI-lab board and the step beyond microcontrollers.
Relay Module
Module
A pre-assembled PCB with one or more relays plus drive transistors, flyback diodes, and optocouplers. Lets a 3.3V or 5V microcontroller safely switch 10A mains or 24V DC loads with a single logic pin.
Motor Driver Module
Module
An H-bridge based module that lets a microcontroller control the speed and direction of DC motors or stepper motors. Handles the high current a motor needs while protecting the logic side with opto or transistor isolation.
Comms Module (WiFi/BT/LoRa/GSM)
Module
Wireless communication modules that add connectivity to a microcontroller. Common types: WiFi for IoT, Bluetooth for short-range, LoRa for long-range low-power, GSM/LTE for cellular.
RTC Module (DS3231 / DS1307)
Module
A watch for your microcontroller: a real-time clock chip with battery backup keeps date and time through power cuts, so your logger timestamps and your alarm fires even after a reboot.
GPS Module (NEO-6M / NEO-M8N)
Module
A complete satellite navigation receiver on a postage stamp: feed it power and sky view, and it streams your latitude, longitude, altitude, speed and atomic-clock time over serial as NMEA sentences.
