110/220V 60W 12V 5A Miniature Switching Power Supply (Mini 12V5A power supply)
A switching power supply is one of the two major types of power supply design utilized in electronics products. These power supplies are characterized by the use of precise switching that allows for designs to accommodate DC to DC, DC to AC, AC to DC and frequency conversions.
In switching power supply designs, the input voltage is no longer reduced; instead, it's rectified and filtered at the input. Then the voltage goes through a chopper, which converts it into a high-frequency pulse train. Before the voltage reaches the output, it's filtered and rectified once again.
Specifications
- Input Voltage: AC110V/220V±15%
- Ouput Voltage: DC 12V
- Output Current:5A
- Shell Material: Metal case
- Safety Compliance: FCC / CE
- High price-effective, reliability with industry standards
- Built-in over voltage, over current, and short circuit protection
- Working Temperature: 0~40C
- Storage Temperature: -20~60C
- Ambient Humidity: 0~95% Non-Condensation
Features
- Switch power supply, convert AC 110V/240V to 12V
- Wide input voltage range, steady and precise output voltage.
- Shortage protection, overload protection over voltage protection.
- Widely used as the power adapter for Led strip, LED display, billboard, industrial equipment, etc.

Geekcreit® 3D Printer A4988 Reprap Stepper Motor Driver Module (red stepper driver)
A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.
A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.

At the core of this module is the ESP32-D0WDQ6 chip*, same as ESP-WROOM-32 module. Compared to ESPWROOM-32, ESP32-WROVER has an additional SPI Pseudo static RAM (PSRAM) of 32 Mbits. As such, ESP32- WROVER features both 4 MB external SPI flash and 4 MB external PSRAM. The ESP32-WROVER module has a PCB antenna, while the ESP32-WROVER-I uses an IPEX antenna. The information in this datasheet is applicable to both of the two modules. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power coprocessor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C.
The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted, and that the module is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP32 supports a data rate of up to 150 Mbps, and 22 dBm output power at the antenna to ensure the widest physical range. As such the chip does offer industry-leading specifications and the best performance for electronic integration, range, power consumption, and connectivity. The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that developers can continually upgrade their products even after their release.
