| 2019-06-13 15:04:16 | rev. 5 | CORRECT | APPROVED | |
| 2019-07-05 14:46:23 | rev. 5 | CORRECT | good | APPROVED |
| 2019-11-07 22:40:08 | rev. 5 | ERROR FIXED | On the B-Key pinout, pins 29, 31, 35, 37 you are showing PCIe Lane 1, but on other devices I have worked with, these pins have USB3.0 TX-, TX+, RX- and RX+ respectively. | APPROVED |
| 2021-07-14 21:06:18 | rev. 6 | ERROR FIXED | I think pin 23 in the Key E table is used and not removed for keying like the table says. | APPROVED |
| 2021-08-19 16:50:23 | rev. 6 | CORRECT | It would be nice to have a reference image for A,E and AE keys with the pin number defined. | APPROVED |
| 2021-08-30 21:01:16 | rev. 6 | ERROR FIXED | This does not show the full pinout for M.2 B Key modules. The M.2 B Key configuration also supports USB SS peripheral which is often used by LTE/GPS modules that almost exclusively use the B-key configuration. | APPROVED |
| 2021-10-06 09:52:41 | rev. 6 | CORRECT | APPROVED | |
| 2022-01-04 16:54:14 | rev. 10 | CORRECT | APPROVED | |
| 2023-01-24 18:32:19 | rev. 10 | CORRECT | APPROVED | |
| 2024-01-15 10:12:11 | rev. 10 | CORRECT | nope :) | APPROVED |
| 2024-03-20 00:01:51 | rev. 10 | CORRECT | APPROVED | |
| 2025-03-07 23:27:09 | rev. 10 | CORRECT | nope | APPROVED |
| 2025-03-25 15:22:07 | rev. 10 | INCORRECT | The Key M pinout has pins labeled as CONFIG_# when this is not what the PCI-SIG M.2 specification calls out. The Key B pinout uses these pins as Configuration pins, but Key M they are called out as GND. These would be pins 21 (CONFIG_0), 69 (CONFIG_1), 75 (CONFIG_2), and 1 (CONFIG_3) which should all be GND on the M-key pinout. | WAITING FOR APPROVAL |
