LC29H modules firmware needs for test


I’ve ordered this module

Is this a mass production module?

Can I get the latest firmware for it? Currently I have the following:
F1: 0000 0000
V0: 0000 0000 [0001]
00: 0000 0000
U0: 0000 0001 [0000]
T0: 0000 00B7
Leaving the BROM



Hi Carlitos,

LC29HAA will become a mass production in this month. You can get the project information from
Quectel_GNSS_Module_Product_Overview_V4.4.pdf (3.6 MB)

Best regards.


is there any low power modes application note for this module?

Hi Carlitos,

LC29H has Backup mode which keeps power supply for backup domain( RTC & RAM ).

Dual-band module unavoidably have high power consumption. If your product mainly work in low power condition, I suggest you to choose LC76GPA ( low power consumption, single-band, not support I2C ).

Chinese new year is coming, and we will have a one-week holiday from tomorrow. Please forgive the absense for your query. Thanks.

Best regards.

thank you very much Raphael and enjoy your Chinese new year! :slight_smile:

Can you give me some information about LC76GPA? any docs I can refer?
Can you also attach for the LC29H the document from where did you take the snapshot?

thanks in advance

Hi Carlitos,

How to debug LC76GPA is mostly same to LC76GAB( single-band, common consumption version ) , so you can refer to LC76GAB documents. The main difference between the two model, is that LC76GPA does not support I2C interface.

Best regards from new year greeting.

Are you sure LC76GPA does not support I2C? The modules I have do support I2C communication.

Hi Rastik,

According to the latest document Quectel_LC76G_Series_Hardware_Design_V1.1.pdf (release date: 2023/02/09 ), LC76G series support I2C function. So LC76GPA do support I2C.
Thank you for your correction.

Best regards.
