ESP32-S3-DEVKITC-1-N16R8V is an Espressif ESP32-S3-DevKitC-1 v1.1 development board based on the ESP32-S3-WROOM-2-N16R8V module. It provides dual-core ESP32-S3 processing, 2.4 GHz Wi-Fi, Bluetooth LE, 16 MB Octal SPI flash, 8 MB Octal SPI PSRAM, USB programming/debugging, native USB OTG/JTAG capability, onboard power regulation, and two 22-pin 2.54 mm header rows for prototyping. Note: on this WROOM-2/N16R8V variant, GPIO35, GPIO36, and GPIO37 are used internally for Octal SPI flash/PSRAM and are not available for external use; GPIO38 drives the onboard RGB LED on v1.1 boards.

The TPS63802DLAR is a highly integrated synchronous buck-boost DC-DC converter designed to provide a regulated output voltage when the input voltage is either above, below, or equal to the desired output voltage. The device automatically transitions between buck and boost operating modes to maximize efficiency across a wide input range. It is optimized for battery-powered and portable electronic applications requiring high power conversion efficiency, low quiescent current, compact solution size, and stable operation under varying load conditions. The TPS63802DLAR is commonly used in wearable devices, IoT products, wireless modules, sensors, handheld electronics, and embedded systems.
