This is Rider @ana.heloisa.77
She can't read yet, but she already rides very well and uses the Gili Pitboard for alerts on the track during training and races. Alerts are made through symbols, facilitating communication between the team and the rider.
The Gilimoto Pitboard / Communication Board has two sides: a blackboard for writing with chalk and a whiteboard for writing with a marker. Both sides are reusable; just wipe them clean with a damp cloth.
The board is sold complete with chalk + marker + cloth, ready for use.
