WSAL24004 – Pico-Sensor-Kit-B/en

Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The Pico-Sensor-Kit-B is an all-in-one beginner kit with a Pico expansion board and 15 modules (LED, button, buzzer, IR, RGB, I2C sensors, ADC inputs). Modules are connected via PCB castellated holes without soldering or wiring; they can be detached and wired as needed.

Technical overview

• Composition: 15 modules on one expansion board in an all-in-one design, no soldering or wiring required.
• GPIO assignments: D0=button, D1=LED, D2=buzzer, D3=IR receiver, D4=IR transmitter, D7=RGB LED.
• I2C0 devices: 6-axis sensor (address 0x6B), VOC sensor (0x59), EEPROM (0x50), temperature/humidity sensor SHTC3 (0x70), motor driver (0x40).
• I2C1 device: 1.5-inch OLED display, 128×128 resolution, 16 grayscale levels (address 0x3D).
• ADC inputs: ADC0=photoresistor (light level), ADC1=potentiometer (simulated voltage changes), ADC2=sound sensor (ambient sound level).
• Power: onboard DC-DC provides 3.3 V at up to 2 A; the motor driver should use external power for better stability.
• Development environments: MicroPython (Thonny IDE), C/C++ (VS Code + pico-vscode), and Arduino IDE are supported.
• Example demos cover GPIO, PWM, I2C, ADC, and PIO functions, including LED, buzzer, OLED, sensors, and motor driver.

Notes and version constraints

• Watch for sharp edges and fragments when detaching the modules.
• The motor driver may overload the 2 A onboard supply; an external power source is recommended.
• Flashing firmware: Pico2 firmware from the MicroPython package may make the device unrecognized; use the firmware provided in the package instead.
• OLED display shows noise/garbled data in the lower half – likely caused by the I2C speed setting in the code; increase the speed and retest.
• Exact command-line commands and script paths depend on the chosen development environment and must be verified before use.
