Thank you for viewing. iRig BlueBoard, sold as is. It's the older micro-USB type. I tried to update it, but it didn't work. Currently, when I turn it on, the D button flashes and nothing works. The product is already registered, so transfer is not possible. The outer box is torn. Would this be suitable for someone who can repair it or for parts? Please consider this only if you fully understand the above condition. Bluetooth connection controller, easy operation with 4 buttons. - Model Name: iRig BlueBoard - Function: Bluetooth - Number of Buttons: 4 buttons (A, B, C, D) - Connection Terminals: USB terminal - Color: Black IK Multimedia iRig BlueBoard Switcher MIDI
