Made this for my Fatsharks. The design is a DC power supply module, which includes a DC-to-DC converter, an LDO regulator, and a voltage monitor. It also features a battery status LED indicator. The board measures 30mm x 20mm. The components used are surface-mount technology (SMT) devices, with the exception of the connectors, which are through-hole parts. Here is the list of components: * DC-DC Converter: U1 - Texas Instruments TPS63050 * LDO Regulator: U2 - Texas Instruments TPS63050 * Voltage Monitor: U3 - Analog Devices ADUM1200 * Battery Status LED Indicator: D1 - Vishay VSMB1116-33 The board can be powered from a 12V or 15V battery. The DC-DC converter provides an output voltage of 5V, which is regulated by the LDO regulator to 3.3V. The voltage monitor monitors the input voltage and indicates it on the battery status LED indicator. Here are some technical specifications: * Input Voltage: 12V or 15V * Output Voltage: 5V (regulated to 3.3V) * Efficiency: Up to 90% * Size: 30mm x 20mm The design uses a 4-layer PCB with the following layers: * Layer 1: Ground plane * Layer 2: Power plane * Layer 3: Signal layer * Layer 4: Top layer (component side) Here is the list of materials used for the board: * FR-4 PCB material * Copper foil thickness: 1 oz The design includes a few features to make it easy to use: * A battery status LED indicator that shows the input voltage. * A DC power supply output connector for connecting devices. * A DC power supply input connector for powering the module from a battery. Overall, this design provides a reliable and efficient DC power supply solution for your Fatsharks.
