Девайс HabrScore для хаброзависимых с блекджеком и …

Raspberry Pi Pico W — это плата микроконтроллера на основе микроконтроллера Raspberry Pi RP2040. Он имеет два ядра ARM Cortex-M0+, работающими на частоте до 133 МГц, 256кб RAM, 30 GPIO и большим количеством разнообразных интерфейсов. Для хранения прошивки и данных используется флеш память 2 Мб для кода и данных.

Характеристики:

• USB 1.1 с поддержкой устройства и хоста
• Низкомощный режим сна и спящий режим
• 26 многофункциональных контактов GPIO
• 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × управляемых ШИМ каналов
• Часы реального времени (RTC)
• Датчик температуры
• Ускоренные вычисления с плавающей точкой на чипе
• 8 программируемых I/O (PIO) портов для пользовательской периферийной поддержки
• Wi-Fi модуль
  Входное напряжение питания:
  • Через USB: 5 В
  • Через пин VSYS: 1,8–5,5 В
• Напряжение логических уровней: 3,3 В
• Потребляемый ток: до 140 мА
• Размеры: 52,7×21×12,3 мм
