EPL-100 TCON Controller Board

The Digital View EPL-100 controller board is designed for E Ink 25.3" and 28" epaper display panels. This low power interface accepts a bitmap image transferred over USB from a source media player such as a Raspberry Pi or Android PC. E Ink based displays are ideal for public signage, the significant benefits include the high visibility in bright environments as well as the ability to operate from solar power due to the very low power consumption.

See the connection guide below, after the Specifications

Options: Custom controller board layout with additional functions or integration is available as an engineering service. In addition Digital View can assist with display bonding and other integration requirements for the E Ink panel.

Power

Power input 12V DC
Power output (option): 5V DC

Standby power consumption (as meaasured):

• 25.3” Panel + EPL-100: 0.06A x 12VDC = 0.7W
• 28” Panel + EPL-100: 0.06A x 12VDC = 0.7W
• Digital View STM-100
• Raspberry Pi3 (Model B+) = 0.32A x 5VDC = 1.6W

During image write to panel (as measured):

• 25.3” Panel + EPL-100: 1.2A x 12VDC = 14.6W
• 28” Panel + EPL-100: 0.8A x 12VDC = 9.7W
• Digital View STM-100
• Raspberry Pi3 (Model B+) = 0.61A x 5VDC = 3.05W
