| CORRECT | APPROVED | |||
| CORRECT | The connections displayed here agree with the connections I plan to make. | APPROVED | ||
| INCORRECT | The pinout for the compact flash connector is ambiguous. It is not keyed, and therefore impossible to tell the top from bottom. | APPROVED | ||
| CORRECT | I spent a lot of time while dismantled CF and checked key assigment. Finally i found simple solution what works- so here is Tip how to know which keys are 1-25 and 26-50: It is known that CF keys 1, 25, 26, 50 is grounded (still mirror riddle) and only one more grounded key 33 is answer. If you look picture how Female connector looks, then key 33 is 8ht hole from left in upper-row. Now just get a chain-link using your resistance-tester for any key 1, 25, 26 or 50 to this 8ght hole by turning CF card upsidedown. When you got link, then you know where is key 33, so left is 26, right is 50 and down-left is 1 and down-right is 25. Note: use picture from this side for pin assigment. | APPROVED | ||

| 2009-01-06 16:38:02 | rev. 3 | INCORRECT | DMA pinconnection missed | APPROVED |
| 2009-01-26 11:26:26 | rev. 3 | INCORRECT | I did all the pin to pin from this connector to the ide one. Unfortunately, it does not work. it damaged the IDE port on the chipset i was runing it into. Do not trust this pin layout. | APPROVED |
| 2009-12-20 21:52:48 | rev. 3 | CORRECT | Absolutely correct. You have to make sure that your CF slot is connecting to a real IDE port of course, but in my case (embedded system) this pinout worked perfectly. | APPROVED |
| 2013-01-29 04:28:38 | rev. 3 | CORRECT | Works perfectly. | APPROVED |
| 2013-10-26 01:17:01 | rev. 3 | CORRECT | This page helped a lot! I made the Modification, now it works. Thank you very much! | APPROVED |
| 2014-01-05 20:26:37 | rev. 4 | CORRECT | The information given here is absolutely correct! I verified this as follows: On an Ide-to-CF-adapter I bought, every connection was exactly like described here; BUT the two DMA-connections (CF43-Ide21 and CF44-Ide29) were different; this caused Windows and Linux to hang shortly after beginning to boot from my CF-card. After I changed these two DMA-connections of my adapter as mentioned here, Windows and Linux run without any hassle from my CF-card! Thank you very much for this helpful page here! (And many thanks also to http://www.fccps.cz/download/adv/frr/cf.html, who describes the problem of the missing DMA-connections on Ide-to-CF-adapters in deep and as a solution links to this page here.)

| 2008-11-27 22:06:55 | rev. 3 | ulis | I made comment how to know where is 1-25, 26-50 pins and now i have mede some mistype corrections, nothing more (swap 8gt ->8th; from this side->site, better pinouts.ru) |
| 2009-03-01 22:45:10 | rev. 3 | DMA connections missed | |

| 2019-11-18 21:41:43 | rev. 7 | Ярослав | Стоит добавить в описание CFразъема здесь и по сайту, что широкий ключ возле 1-го(26-го) пина, а узкий - 25(50). |
