Hello,for one of our customers in the sector of process automation, we are evaluating different BLE modules including your BlueNRG-M2SP and BlueNRG-M2SAFor our evaluation, there are two requirements we must know, to verify their capability to be certified and used it in explosive environments (ATEX):Internal (onboard/on chip) total capacity (C) and inductivity (L). This can be either a list or partial BOM of all capacitors and inductors included in the module, or its schematicsIs this module washable after its assembly on the target PCB, to be prepared/cleaned for a final coating or potting?I hope you can provide me with this information.Best regardsAchim

Question

Q1: For the modules BlueNRG-M2S(P) and (A): What ist he sum of capacitors (µF) and inductances (µH) in each module (is required for ATEX certification)? Q2: Are these modules washable after assembly on the PCB, for subsequently coating/potting ?

Hello,

for one of our customers in the sector of process automation, we are evaluating different BLE modules including your BlueNRG-M2SP and BlueNRG-M2SA

For our evaluation, there are two requirements we must know, to verify their capability to be certified and used it in explosive environments (ATEX):

Internal (onboard/on chip) total capacity (C) and inductivity (L). This can be either a list or partial BOM of all capacitors and inductors included in the module, or its schematics

Is this module washable after its assembly on the target PCB, to be prepared/cleaned for a final coating or potting?

I hope you can provide me with this information.

Best regards

Hello,

You are right.

Atex certification requires to know some module internal details.

This cannot be provided over community so I would encourage you to contact your local ST sales representative or distributor.
