A low cost version is available with pared-down hardware to make it more affordable. Still use it with MakeCode Arcade. The low-cost 3939 version has the same processor chip, QSPI Flash, on/off switch, buttons, buzzer, light sensor, and battery circuit. This board does not have Feather headers, JST STEMMA connectors, a LIS3DH accelerometer, or an optional speaker connection. Instead of five NeoPixels there is only one in the center front.
The MakeCode Sync Cable is a Micro B USB to Micro B USB cable that is specifically designed for co-op fun or player-versus-player showdowns. This cable is compatible with PyGamer, and the JACDAC pin is connected to the extra ID pin of the Micro B cable so data can pass back and forth.
