    a: 'Yes. Velxio is completely free and open-source (GNU AGPLv3). Simulate RP2040 code in your browser — no Raspberry Pi hardware needed, no account, no payment.',
  },
  {
    q: 'How does the RP2040 emulation work?',
    a: 'Velxio uses rp2040js — the open-source RP2040 emulator — to simulate the ARM Cortex-M0+ CPU at 133 MHz. Your code is compiled with the official Arduino-Pico core by Earle Philhower.',
  },
  {
    q: 'Does it support Raspberry Pi Pico W?',
    a: 'Yes. Both Raspberry Pi Pico and Pico W are supported. The RP2040 core emulation is identical — WiFi features are planned for a future update.',
  },
  {
    q: 'Can I use Arduino code with Raspberry Pi Pico?',
    a: 'Yes. Velxio compiles your .ino sketch using the arduino-pico core (by Earle Philhower). Standard Arduino functions like Serial, digitalWrite, analogRead, and I2C/SPI work out of the box.',
  },
  {
    q: 'What components work with Pico simulation?',
    a: 'All 48+ components: LEDs, resistors, buttons, DHT22, HC-SR04, servo motors, 7-segment displays, RGB LEDs, NTC sensors, joysticks, and more. Wire them to any of the 26 GPIO pins.',
