@Sjito yes, It should be a LSM303AH. The "903" refers to the year and to the week "YWW", while "03A" is part of the name "LSM303AH". Btw, you can be sure it's a LSM303AH checking the WHO_AM_I_A (0Fh) register via SPI/I2C and receiving 43h. Regards

Hi @Sjito , which is the purpose for this request about device marking? Do you need the meaning of the info on the top side of the marking? They are related to the process flow of the single device, from assembly to finishing. Regards

Thank you very much for your reply.I can safely use the one I bought.But I wonder how you know this information(The "903" refers to the year and to the week "YWW", while "03A" is part of the name "LSM303AH".)? Whether there is a document about it ? Looking forward to your reply.

You're welcome. There is no official document because the package information are intended for internal tracking of individual devices. The only information mandatory for a proper pcb project is the pin 1 indicator placement. Regards
