Product Overview
Great IoT products rarely stop at version one. The IoT Expansion Board PCBA is a flexible GPIO breakout module designed to extend WiFi IoT development boards with additional sensors and actuators - built for the iteration cycles of rapid IoT product development.
Brightlx produces IoT expansion PCBA boards, GPIO breakout modules, sensor interface boards, and IoT prototyping boards featuring I2C/SPI/UART interfaces, power management, and compact form factor. Layout options cover popular form factors including Arduino shield compatible and Raspberry Pi HAT compatible footprints, with stackable headers, level shifting for 3.3V/5V mixed-voltage systems, and dedicated Grove and Qwiic connector versions for plug-and-play sensor chains. Breakout routing supports ADC, PWM, and interrupt-capable pins with clearly labeled silkscreen, making these boards ideal for smart home IoT expansion boards, wireless sensor interface modules, IoT actuator control boards, and wearable prototyping boards.
From custom PCB design for a new IoT expansion board, through custom PCB assembly for prototype production, to full turnkey manufacturing, Brightlx provides customized PCBA solutions, OEM services, SMT assembly, and 100% functional testing with connectivity verification on every outgoing board. With 16 years of PCBA assembly experience, we are your one-stop partner for IoT expansion boards and development modules.
