Features: The voltmeter resolution: ±0.1V The voltmeter digital display range: 0V - 45V The voltmeter input voltage range: DC 4V - 40V Output voltage: continuous adjustable (1.3V -37V) Output current: 2A (Max 3A) Size:65 x 35mm Description: With terminal block Over-heat protection and short circuit protection function LED digital voltmeter tube, it can adjustable accurate aimed at your multimeter. Press the key "S1" to let the display show the input or output voltage. when the green led light, it shows output, the red show input. Touch the button to switch the measurement input or output voltage, and indicator light shows which voltage is being measured, it can save the settings, even if the power off and restart. Using 150KHz internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption and high efficiency. Note: To guarantee the accuracy of the voltmeter, make sure the input voltage above 4V. The input voltage must be 1.5V higher than the output voltage or 1.5V above. Package included: 5 x LM2596 DC-DC 1.3V -37V 3A adjustable buck power module

Description: Note: This module does not suitable for IOS system. The core module HC-06 main modules, leads the interface includes VCC, GND, TXD, RXD, KEY pin high trigger to clear the pairing information re search led indicate Bluetooth connection status, flash unpaired slow flash indicates paired but not slave connection, Always follow machine connected Backplate settings LDO input voltage of 3.6~~6V unpaired current is about 30mA, paired 10mA, input voltage prohibit more than 7V absolute prohibition of reverse power! Interface level 3.3V, can be directly connected the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be connected directly, without MAX232 can not go through the MAX232! Open to effective distance of 10 meters, over 10 meters is also possible, but not of this the quality of the connection of the distance do to ensure The pair later when full-duplex serial use, do not need to know anything about the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format does not support other formats. Support to establish a Bluetooth connection through AT commands set the baud rate, passkey, set parameters are saved after. Bluetooth connection is automatically switched to the pass-through mode. Wireless serial Bluetooth port with free extension cable. With transparent shrink tube, dust and beautiful, and there is a certain degree of anti-static capabilities. Size:3.57cm x 1.52cm Tips: TXD: the sender, usually expressed as its sender, the normal communication must be connected to another device RXD. RXD: the receive side, generally expressed as the receiving end of their normal communication to another device connected to TXD. Package included: 5 x HC-06 wireless bluetooth transceiver
