Boardoza TPS62A02N 3.3V Synchronous Buck Regulator Breakout Board

This board is designed based on the Texas Instruments TPS62A02N device and implements a synchronous step-down (buck) DC/DC converter optimized for high efficiency and compact form factor. The device integrates power switches capable of delivering up to 2 A of output current. Under medium to heavy load conditions, the device operates in pulse-width modulation (PWM) mode at a 2.4 MHz switching frequency. At light loads, it automatically transitions to power-save mode (PSM) to maintain high efficiency across the entire load current range. Shutdown current consumption is minimized. An integrated soft-start circuit limits inrush current during startup. Additional built-in features include overcurrent protection, thermal shutdown protection, and an optional power-good function. Applications Industrial Control and Automation Systems - 2 A output capability can power sensor arrays and actuators. - Suitable for motor driver circuits, relay boards, and other medium-power industrial applications. IoT and Data Acquisition Systems - Provides locally regulated, low-noise power for microcontrollers, sensors, and wireless modules, improving measurement accuracy and system stability in IoT and data acquisition applications. - Compact and efficient power solution enables distributed sensing nodes, where point-of-load regulation is required close to the load. Prototyping and Educational Platforms - 40 mm × 20 mm size allows integration of multiple regulators, sensors, and MCU modules. - Ideal for circuit design testing and educational purposes. Battery-Powered Medium-Power Applications - Provides stable power for portable devices and field prototypes.

Boardoza ESP8266 8-Channel Hybrid Wi-Fi Relay Breakout Board

The Boardoza ESP8266 Relay Board is a high-performance, network-connected load switching platform designed for versatile smart home and industrial IoT automation. Built around the ESP8266 wireless SoC (ESP-07S) with 2.4 GHz 802.11 b/g/n Wi-Fi connectivity, the board features a hybrid switching stage integrating four zero-cross solid-state relays (Panasonic AQH3213A) and four high-capacity electromechanical power relays (Panasonic ALQ105). The optically isolated SSR channels support up to 600V peak off-state voltage and 1.2A RMS with built-in RC snubbers for silent, wear-free, and sparkless AC load switching, while the SPDT mechanical relays switch heavier loads up to 10A at 125VAC or 5A at 250VAC / 30VDC using discrete MOSFET drivers and LED indicators. To ensure safe and standalone deployment directly from mains power without external adapters, the board integrates an isolated AC-DC power converter protected by an onboard fuse, line filter, and high-voltage varistor, backed by a local 3.3V LDO regulator rail to deliver a robust, all-in-one multi-channel control solution. The board is ideally suited for deployment across industrial automation, smart building infrastructure, commercial facility systems, agricultural automation, and remote energy management.

Boardoza NE555 Adjustable PWM Dimmer Breakout Board

This board is an adjustable PWM (Pulse Width Modulation) control board designed to generate a PWM signal using an NE555 timer IC and apply this signal to the output through a PMOS power MOSFET. The board is designed to operate with a 5–16 V DC supply voltage. The PWM duty cycle can be adjusted using the RV1 potentiometer. Diodes D1 and D2 provide separate charging and discharging paths for the timing capacitor, allowing independent adjustment of the PWM duty cycle. The PWM signal generated by the NE555 controls the gate terminal of the Q1 PMOS power MOSFET. As a result, the supply voltage is switched to the output according to the PWM signal. The primary purpose of the board is to provide PWM-based power control for DC loads. By adjusting the PWM duty cycle, the average power delivered to the load can be controlled without continuously regulating the supply voltage.

Boardoza TPP38002 5V Isolated Power Supply Breakout Board

The TPP38002 Isolated Power Supply Board is designed to provide non-isolated and galvanically isolated 5 V power from a single input. It operates from a 6–32 V input and delivers up to 500 mA from the non-isolated output and up to 200 mA from the isolated output. Since the regulator’s feedback is taken from the non-isolated output, the isolated output current is limited to 200 mA in this design. The board is suitable for industrial systems, interface circuits, and applications that require an isolated auxiliary supply.
