Not yet, the module has no issue with EMI tests though. It is a 4 layers PCB with 3 ground planes. Certifications are required per finished product no matter the components inside are certified are not.

Is it TELEC, FCC, EC, IC Approved?

cool - thanks - may be looking for a module for a couple of prototypes in May/June, the new one would work nicely.

The current IMM-NRF51822 has 16MHz Crystal, LDO, no 32KHz, 16KB ram.
The new module IMM-NRF51422 16Mz & 32KHz Crystal, DC/DC, 32KB ram. This module is ready for production but got delayed since March due to shortage of the nRF51422-QFAC chip. It will be available within May. It will have same footprint and i/o pin map as the current module except 2 pins used for the 32KHz crystal which are now in use.

Does that IMM-NRF51822 Micro-Module have the 16MHz and 32KHz crystals on it, I couldn't tell. How about the new module you mention, and when's that coming out?

This module here offers full i/o. A new module with using nRF51422 32KB ram with same footprint will be avail in may. It will be fully loaded with 32KHz crystal & DC/DC power mode support.

Many thanks Alex. Can you tell me about the other modules (with less IOs)?

MDBT40-256R link text It has maximum IOs. There are some other modules with 256/32 spec but not all IOs connected to pins
