Depends on what kind of certification you are asking for. Is it component level or product level? Development boards are targeted for engineers to try firmware and some hardware testing before developing actual application board. Development boards generally do not cover certification aspects. If you are working on development board and want to have that edge in the market prefer to have certification related specifications at the cost of higher board price though.

1. 220 ohm resistor from the base of BD139 must be higher value?
2. This circuit consumes much higher power than 1W?
