It looks like there is Arduino support for the STM32... That might be easier than a hardware redesign. https://www.stm32duino.com/ On Thu, Mar 13, 2025 at 9:46 AM nick via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > The CAPE team is considering flying an EXPRESSIVE 32 or an Arduino unio r4 > type processor instead a STM32 .

The CAPE team is considering flying an EXPRESSIVE 32 or an Arduino unio r4 type processor instead a STM32 . Does this group have any comments. The reason for the change is to have a shallower learning curve for our new members and many schools in area use the Arduino IDE. nick Cell 337 258 2527 Helping UL become a world Class Engineering and Educational School Disagree I Learn

by Félix Páez 13 Mar '25

13 Mar '25

Dear friends, This is just to update you that the launch for our HADES-ICM satellite is scheduled for this Saturday March 15th. It has the same functionalities as in HADES-R (SO-124). FM and Digital modes repeater with Uplink on 145.875 MHz and Downlink on 436.666 MHz. It also carries the same experiment for SMART-IR/Manchester University. The repeater will no be active until all the checks have been performed on the satellite. This can take several weeks Thanks all for your support. Received telemetry is appreciated. The same demodulator and decoder for HADES-R is compatible for HADES-ICM. Félix EA4GQS (AMSAT-EA)

Re: CubeSatSim Kits at the AMSAT online store right now until they run out
by Pat Kilroy 12 Mar '25

https://cubesatsim.org/papers/ Hello Frederick! Thank you for the flattering question about the Technology Readiness Level (TRL) for our humble AMSAT CubeSat Simulator (“CubeSatSim”). None of the electrical, electronic, electromagnetic or mechanical parts or assemblies are rated for any level of flight, although some experimenters have expressed a desire to use their CubeSatSim model as a payload on an Amateur Radio high-altitude balloon (ARHAB) mission. There are no guarantees expressed or implied for successful operation beyond the cozy environment of a classroom, lecture hall, Hamfest or similar, for great demonstrations to the Youth, fellow hams, university student groups, the public and the like. The developers of the AMSAT CubeSat Sim hope that a CubeSat developer of a Flight Model or an Engineering Test Unit whose first step was building one or more of our Sims, would share their experiences here. After your CubeSatSim has “flown” on demos then please be sure to report back your findings! Thank you again and good luck! Sincerely, Pat Kilroy N8PK AMSAT Ambassador Sykesville, Maryland USA https://cubesatsim.org <https://cubesatsim.org/papers/> Pat Kilroy 1 On Wed, Mar 12, 2025 at 7:40 PM Frederick Herrmann via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > It looks quite good!
