249+
[^brickpi-1-version]: The version number is not actually printed on the BrickPi
250+
circuit board.
251+
252+
[^beaglebone-green]: The Grove sensor ports are not usable with EVB or QuestCape
253+
because of shared pins.
254+
255+
[^beaglebone-green-wireless]: BeagleBone Green Wireless is not supported because
256+
of I/O pin conflicts.
257+
258+
[^ev3-color-display]: It is possible to replace the display in the EV3.
259+
[Video.](https://youtu.be/gPNJC5Uz9HY) The color screen is 160x128 pixels,
260+
16 bpp, with adjustable backlight.
261+
262+
[^brickpi-display]: It is possible to stack a display on top of BrickPi.
263+
[Blog.](http://lechnology.com/2016/05/adding-a-display-to-brickpi)
264+
265+
[^evb-buttons]: EVB and QuestCape cannot detect simultaneous button presses.
266+
267+
[^raspberry-pi-sound]: The headphone jack on Raspberry Pi can be used for sound.
268+
269+
[^evb-sensors]: The EVB cannot automatically detect some NXT sensors. NXT sensors
270+
can still be used, but the input port must be manually configured for them.
271+
272+
[^brickpi-ev3-sensors]: BrickPi only supports the LEGO EV3 sensors (Color,
273+
Infrared, Ultrasonic, Gyro, Touch). [The UART sensor implementation is buggy
274+
in the BrickPi firmware.](https://github.com/DexterInd/BrickPi/issues/24)
275+
276+
[^pistorms-ev3-sensors]: PiStorms only supports the LEGO EV3 sensors (Color,
277+
Infrared, Ultrasonic, Gyro, Touch).
278+
279+
[^brickpi-nxt-sensors]: BrickPi has limited I2C sensor support. Most sensors
280+
do work, but there may be some limitations.
281+
282+
[^pistorms-nxt-sensors]: PiStorms shares the I2C communication bus with all four
283+
input ports, so each sensor must have a different I2C address.
