Enjoy funs with its unique design. you can change it as you wish. About Pico Pico is a tiny, fast, and versatile board designed by Raspberry Pi in the UK. Technical Specification Pico is a low-cost, high-performance microcontroller board with flexible digital interfaces. Key features include: *Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz *264KB of SRAM, and 2MB of on-board Flash memory *Castellated module allows soldering direct to carrier boards *USB 1.1 with device and host support *Low-power sleep and dormant modes *Drag-and-drop programming using mass storage over USB *26 × multi-function GPIO pins *2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels *Accurate clock and timer on-chip *Temperature sensor *Accelerated floating-point libraries on-chip *8 × Programmable I/O (PIO) state machines for custom peripheral support Direction Models: To select the active d-pad mode, while the controller is plugged in press: ?DP(Normal D-pad operation): SELECT + START + DOWN ? LS(Left analog stick emulation): SELECT + START + LEFT ? RS(Right analog stick emulation): SELECT + START + RIGHT SOCD Models: ? Up Priority: START + HOME + ?, ? + ? = ?,? + ?= Neutral ? Neutral Priority: START + HOME +?, ? + ? = Neutral ,? + ? = Neutral ? Last Input Priority: START + HOME +? Turbo Model: To select Turbo mode, hold one of the following buttons and TURBO button: ? Available Button - 1P 2P3P 4P 5P 1K 2K 3K 4K ? Speed - 1~60 clicks per minutes Hold Turbo button, and click UP button to speed up, and click DOWN button to lower the speed.Hot swapable switch , you can change the switches as you like. (Please contacat us for manual and latest firmware after order.). The mechanical switch are relatively light and have a soft bump above the actuation point, which makes things somewhat tricky as you may think you have activated the button upon the tactile feel, but you actually have to travel a tad farther from the bump to actuate the switch. Pico is a tiny, fast, and versatile board, a brand new microcontroller chip designed in the UK. low-cost, high-performance microcontroller board with flexible digital interfaces. The box use mechanical switches ,The box is compatible with PC/Android by using Zero Delay Arcade USB Encoder with SOCD Supported. Rtu Mini box mechanical Switches Support PC Xinput DInput Turbo Function This Rtu Mini is a unique controller not only because it allows you to input SOCDs, but it also gives you the the ability to switch among many SOCD Resolutions.
