I am working on a project using: https://wiki.seeedstudio.com/2-Channel-CAN-BUS-FD-Shield-for-Raspberry-Pi/ with RPi4B. We have 3 systems each with one of those Seeed 2-channed (MPC2518FD) board installed and all is working fine. The Seeed boards were purchased through Amazon.
We have recently tried to order a few more of these boards through Amazon but find the board we use unavailable. The Amazon link that used to work now shows an older board. Is there a supply problem with the 2-channel MPC2518FD board (the one with the RTC)?
