@milenko-s:matrix.orgmilenko-sAt LibreSpace no one really noticed the PCDU developments here, now they know and with the release of their COMMS board it is the right time to establish a common connector layout 😃 maybe we should open a PCDU post on the community to make it more visible15:02:05
@sawjan:matrix.orgsawjan They have been using (and greatly improved, thanks for that) our board template. drid has made a few suggestions for the needs of their comms board, and we have included them in here: https://lite.framacalc.org/cubesat_board_connector_pinout 15:08:55
@sawjan:matrix.orgsawjanPending is the introduction of a second/redundant SPI, as well as updating the board template with the I2C and SPI pins.15:10:27
@milenko-s:matrix.orgmilenko-sSo it was just Pierros who was not aware 😅 Great!15:11:29
@sawjan:matrix.orgsawjanIf you scroll a few lines back, you can see part of the exchange on the connector15:12:18

@artur.librecube:matrix.orgArtur ScholzA new revision of the PCDU is just about to be manufactured: https://aisler.net/p/UFKILGLI20:36:31
@artur.librecube:matrix.orgArtur ScholzYes, would be good to think about the connector! There is also an effort from Filip and Nicolas: https://docs.google.com/spreadsheets/d/1i5K-vAvxz3pjaMmevmTFQ7T1QAQMvZJ8UzIaaUw7MgE/edit#gid=020:38:13
@artur.librecube:matrix.orgArtur ScholzThe main point however should be to remain compatible. At least with LibreSpace, but preferably also with COTS boards20:39:09
@artur.librecube:matrix.orgArtur ScholzWho would like to take the lead on that? Also, I think it is still a bit on dispute what to choose for the main system bus. Can we confirm that CAN can be operated at reasonable power consumption? Or should we go for an alternative...20:41:16

Just cross-referenced with our sheet, it seems the ISIS EPS also reserves pins H2-50 and H2-51 by default
You can check https://www.isispace.nl/wp-content/uploads/2019/04/ISIS-iEPS2_0-OS-00001-iEPS_Option_Sheet-1_4.pdf page 3 (ABF) for reference

@artur.librecube:matrix.orgArtur ScholzThe CFDP transport protocol in action! The CFDP engine is here: https://gitlab.com/librecube/prototypes/python-cfdp17:18:13
@artur.librecube:matrix.orgArtur ScholzThe GUI application is here: https://gitlab.com/librecube/prototypes/python-cfdp-gui17:18:24
@artur.librecube:matrix.orgArtur ScholzThis is an implementation of the CCSDS File Delivery Protocol (CFDP). By the way, the ESA Euclid and JUICE missions are going to use CFDP for file transfer.17:20:06
