This is an Arduino-compatible board with integrated 3W stereo amplifier designed for use in arcade projects (like our Picade). It behaves like a keyboard when plugged in via USB and has a default key-mapping (though you can reprogram it using the Arduino IDE). Connections are made using screw terminals for a solid, permanent installation. It uses the same micro-controller as the Arduino Leonardo (the ATmega32U4) and is pre-installed with the Arduino bootloader and our software. Features * Powered by an ATmega32U4 (32KB, 2.5K RAM @ 16MHz) * 6-pin ISP header for direct programming (also pre-loaded with Arduino bootloader) * Includes a stereo 3W amplifier (PAM8407) for use with 4? speakers * Appears as a USB HID device (keyboard) to the host * Screw terminal contacts for four-direction Joystick, 12 buttons, and two speakers * Reset button * Mounting holes * Power, Bootload, TX, and RX LED indicators https://elecena.pl/product/22710643/picade-pcb-arduino-compatible-with-3w-amp-discontinued 2023-03-06 https://elecena.pl/product/22710643/picade-pcb-arduino-compatible-with-3w-amp-discontinued 2024-09-19
