I try to connect arduino with M35 . in datasheet RX pin is 21 and TX pin is 22 but when i connect this way
M35 RX -------Arduino TX
M35 TX --------Arduino Rx
Its not working …
But in this way its working :
M35 RX -------Arduino RX
M35 TX --------Arduino TX
The RXD pin number is 22 and the TXD pin number is 21:
Thank you for your reply . I found this wrong pin in M35 datasheets . Could you give me correct pinout for M26 too . I want to design it directly on pcb . Do you have any advise ?Has M35 and M26 big difference ?
do you have link for M35 and M26 footprints?
Could you please tell me the specfic version of the M26 module?
I see this words on them
The M26FB module only has the Chinese version of the HD document.The pin diagram is as follows：
I notice M66 and M26 has same pinout . Currently im not access to M26 so i check it with M66 . Unfortunately in M66 FB Tx and Rx pins are wrong in data sheet . Im confused . I want to do same thing with M26 and change Rx and Tx pins . I want to design it on many pcbs. could you confirm it …
Do you mean you want the pin diagram of M66？If yes, please tell me the specific version of the M66 module
Yes . M66 FB please . Thank you.
Could you give me m26FB datasheet and whats mean of FB and FA?
The M26FB module only has the Chinese version of the HD document.

FA and FB belong to different baseline versions and PA is not the same, the function is basically the same.
Thank you for help . M26 support SSL ?
Please give me the software version of your module(You can use ATI to check).
