is Meshtastic able to work with this board?

Yes. Please refer to this page: https://meshtastic.org/docs/hardware/devices/heltec/

Does this unit have an FCC sticker?

Hi, no, it doesn't have FCC certification.

I bought 2 of these units and am seeing very low rssi(sub -125), even when they are on the same breadboard, w/o antennas around ~100 on same bb.

Dear, have you solve your matter? if not, could you send us some photos of the rssi, we'll take is to discuss with our technicians. Maybe they can help you. Many thanks!
