2/6 Select library parts for MCU, T/RH sensor, USB-C input, regulator, and protection

Rename project, create specification, and record initial requirements/power budget

Select library parts for MCU, T/RH sensor, USB-C input, regulator, and protection

Add main components and supporting passives to the schematic

Wire USB-C power/protection, 3.3 V rail, MCU boot/debug, USB data, I2C sensor, and indicators

Create firmware/regulatory/bring-up project files

Run schematic/design checks and fix actionable issues

Thought for 38 sec
Search Select a low-power Wi-Fi plus Bluetooth LE 5.x MCU module for a USB-C powered consumer temperature/humidity sensor node. Need 2.4 GHz 802.11 b/g/n, BLE 5.x, native USB programming preferred, integrated antenna/certified module, 3.3 V operation, suitable Flux library part..

Generate a schematic for an ESP32 DevKit project with these connections:
  1. Power: Create a 5V rail (from ESP32 VIN), 3.3V rail, and common GND.
  2. I2C (3.3V): Connect MPU6050 and BMP150 in parallel to ESP32 GPIO 21 (SDA) and GPIO 22 (SCL).
  3. Analog (5V): Connect AO pins of MQ135 to GPIO 34, MQ2 to GPIO 35, MQ7 to GPIO 32, and LM35 VOUT to GPIO 33.
  4. UART (5V): Connect Neo-6M GPS TX to ESP32 GPIO 16 (RX2) and RX to GPIO 17 (TX2). Use clean net labels to avoid wire clutter.

No schematic changes were made because no ACUs are currently available.
Remaining work:
  • Add ESP32 DevKit, MPU6050, BMP150, MQ135/MQ2/MQ7, LM35, and NEO-6M.
  • Create labeled 5V, 3V3, GND, I2C_SDA, I2C_SCL, and UART nets.
  • Wire the requested GPIO assignments.
  • Add I²C pull-ups and verify part pinouts.
  • Add level shifting or scaling where required: ESP32 GPIOs are not 5 V tolerant, including ADC and UART inputs.
