WhatsApp Excerpts¶

2023-08-30 05:16 - ~ Josh M: I also thought everything was going to go up? I remember being told during the sessions that they would be posted online for later reference, so I didn't really take notes.
2023-08-30 15:13 - Cam Stewart: Pins 1, 5, 7 and 8 have continuity. The others do not. Is there a HHB pinout floating about?
2023-08-30 18:44 - Cam Stewart: FYI: Pinout located in the “electronics manual”. Looks like we’re missing the RX and TX lines.
