FJ- 433MHz Superheterodyne RF Wireless Acceptor Circuit Module Board for Arduino. In 2003, CU student Nate Seidle fried a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own company. Isolated Power Supplies Transformer Drivers Charge Pumps Linear Regulators LED Drivers Motor Driver ICs Protection and Control System Power Protection USB Power Switches Hot-Swap ICs Display Power and Control LCD Power Control ICs for LCDs Display Drivers Voltage Supervisors, Voltage Monitors, and Sequencers Reset IC/Power-On Reset Multivoltage. Based on the work of Makis, SV1AFN i've build a small, stand-alone power meter with a "nice" GUI. Then the arduino continuously scans the RF module for the pattern. Attach the transmitter through the tap to a dummy load where the output voltage can be read directly using a di-ode detector and DVM as shown in Fig-ure 6. Output is displayed in dBm, Watts (nW, uW, mW and W range) as well as input voltage. Reverse the RF connections so that the dummy load is at the input. RF Input power must be somewhere between 15 and 20dBm (30 to 100mW). These two instructables (1, 2) present an easy way to build a VU meter using an Arduino. Internal link to SIMPLE PEAK WATTMETER BOARD. The controller by the voltage divider R3 and R4 and analog input A1 supervises the state of the supply voltage of 12V and immediately stores the location of the antenna in the memory during power failure. HC-12 Wireless Transceiver Modules 433Mhz are wireless serial port communication modules, It is based on SI4463 RF chip, it has built in microcontroller, and can be configured using AT commands, Maximum output power is 100mW (20dBm) and receiver sensitivity differs from -117dBm to -100dBm, depending on transmission speed. It is powered by the Antenna Tuner port on the Icom radio. Loading Unsubscribe from Jean-Jacques DE REY? Cancel Unsubscribe. 0 Specification.
