== Summary ==<br />
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.<br />

<br />
== Technical overview ==<br />
* Composition: 15 modules on one expansion board in an all-in-one design, no soldering or wiring required.<br />
* GPIO assignments: D0=button, D1=LED, D2=buzzer, D3=IR receiver, D4=IR transmitter, D7=RGB LED.<br />
* I2C0 devices: 6-axis sensor (address 0x6B), VOC sensor (0x59), EEPROM (0x50), temperature/humidity sensor SHTC3 (0x70), motor driver (0x40).<br />
* I2C1 device: 1.5-inch OLED display, 128×128 resolution, 16 grayscale levels (address 0x3D).<br />
* ADC inputs: ADC0=photoresistor (light level), ADC1=potentiometer (simulated voltage changes), ADC2=sound sensor (ambient sound level).<br />
* Power: onboard DC-DC provides 3.3 V at up to 2 A; the motor driver should use external power for better stability.<br />
* Development environments: MicroPython (Thonny IDE), C/C++ (VS Code + pico-vscode), and Arduino IDE are supported.<br />
* Example demos cover GPIO, PWM, I2C, ADC, and PIO functions, including LED, buzzer, OLED, sensors, and motor driver.<br />
<br />
== Notes and version constraints ==<br />
* Watch for sharp edges and fragments when detaching the modules.<br />
* The motor driver may overload the 2 A onboard supply; an external power source is recommended.<br />
* Flashing firmware: Pico2 firmware from the MicroPython package may make the device unrecognized; use the firmware provided in the package instead.<br />
* 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.<br />
* Exact command-line commands and script paths depend on the chosen development environment and must be verified before use.<br />
