AIoT SenseNode - Next Generation IoT Platform

AIoT SenseNode Flexible Power:
--> Can be powered by USB-C connection or single cell Lithium Ion or Polymer battery
--> Onboard charging and battery monitoring circuits
--> There is a second charging port (max 7V) for battery charging power sources such as solar panel, inductor charging, or general DC source
--> Automatic power switching / isolation so all power sources can be connected. When USB-C is connected it is used a primary power source and battery charging source
--> Design consists of 5V and 3.3V power rail that can be accessed via external circuits

AIoT SenseNode Measurement Capabilities:
--> External high accuracy Sigma Delta 12-bit ADC, that consists of 4 single ended or 2 differential measurement channels
--> The ADC has an input programmable gain amp that allows the user to adjust the voltage measurement range to maximize measurement resolution
--> The ADC interfaces with the ESP32 via I2C communication
--> A battery monitoring IC allows tracking of battery current (charge and discharge), battery voltage, and battery power.
--> The battery monitoring circuit can serve as a fuel gauge, allowing you to monitor the battery's state of charge, charge rate, and discharge rate
--> The battery monitoring circuit interfaces with the ESP32-S3 via I2C communication

Summary of ESP32-S3 Features:
--> Xtensa® 32-bit LX7 dual-core processor that operates at up to 240 MHz
--> 2.4 GHz Wi-Fi (802.11 b/g/n), Bluetooth Classic + BLE 5.4, and the ESP-NOW protocol for creating small low power mesh networks
--> MCU supports vector instructions, which provides acceleration for neural network computing and signal processing workloads. Compatible with ESP-CLAW edge AI agent framework
--> Peripherals: GPIOs, SPI, I2S, I2C, PWM, RMT, ADC, DAC and UART, SD/MMC host and TWAI™
--> Deep and light sleep low power modes with real time clock (RTC) timing control

Communication, programming, and other features:
--> USB C interface supports UART communication with the ESP32 as well programming the ESP32-S3 with just a USB cable
--> 6 pin interface can connect to the ESP-Prog for programming and debugging the ESP32-S3
--> Includes a QWIIC connector with 3.3V power and I2C communication to easily interface with Sparkfun and Adafruit sensor boards
--> Onboard RGB LED that interfaces with the ESP32-S3
--> Power down pin, when actively pulled low all power buses are turn off

See the AIoT SenseNode getting started page for a detailed descriptions on pins and features.
