the source code for the mim module has now been
released to encourage further production of this
small tnc aprs transmitter on a chip. this is the
same chip used in the mic-e project and the protocol
was later used in the d7 and d700 radios.
http://www.ew.usna.edu/~bruninga/mim2.htmlthe mim module was developed by wb4apr, n3mim,
and n3xlm and used in many balloon and small
satellite projects over the years.
it provides these tnc transmit functions:
* beacon text
* gps position data
* 5 channels of analog telemetry in aprs format
* up to 8 bits of parallel bit data
* full implementation of the mic-e format
* cw id for balloons
one of these modules is sufficient to provide all
the telemetry as used on pcsat, pcsat2, ande
and raft1 satellte missions. thus, they are
ideal for small satellites such as cubesats
pioneered at stanford.
by releasing the source code, we hope this will
encourage further production of these excellent
telemetry modules for tiny satellites.
