Enjoy funs with its unique design. you can change it as you wish. About Pico board Pico is a tiny, fast, and versatile board designed 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.). We use Mechanical Sliver Switches in the mechanical buttons of this mini box. They 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 built using 2040, 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 Speed Silver Switches Support PC Xinput DInput Turbo Function This Rtu Mini box 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.
