How does the MRC11 compare with H.board?
When connected to the MRSX01sensor expansion board, the MRC11 allows you to control two DC motors with H-bridge motor controllers (more robust than the H.Board) and two servos with male headers on the board for easy connection (not available on the H.Board). The MRSX01 supplies 24 multiplexed analog inputs, with 2 unused, memory-mapped output select lines and 4 unused, memory-mapped input select lines for connecting input and output devices. The MRSX01 provides a recharge circuit to recharge NiCd batteries, a 5-bit and a 4-bit digital-to-analog-to-digital conversion units. These conversions are non-linear, but unique. For example, a 5-bit digital input will produce a unique 8 bit number which, if desired, can be converted to the same 5-bit input. Essentially, one analog port serves as a 5-bit digital input port. The same description applies to the 4-bit digital-analog-to-digital conversion unit. The MRSX01 also has an 8-bit digital output register whose outputs can be modulated at 40KH
