$25 TTGO T5 4.7-inch e-Paper Display comes with ESP32 WiFi & Bluetooth SoC

We’ve very recently covered M5paper IoT development kit based on ESP32 WiSoC, and equipped with a 4.7-inch touchscreen e-Ink display together with a 1,150mAh battery all nicely packed into an enclosure.

It looks great, but costs $69, so if you’d like to integrate this type of ESP32 connected display into your own project at a lower cost, you may be interested in TTGO T5 4.7-inch e-Paper display with 16 gray levels fitted with an ESP32-WROVER-E module with 16MB flash, and 8MB PSRAM.

TTGO T5 key features and specifications:

LilyGO provides two version of the board: one with connectors for the 18650 battery, and one without for people preferring to use a LiPo battery. While there’s a 6-pin touchscreen connector, LilyGO does not appear to offer a touchscreen at this time.

The company says the display can be programmed with the Arduino IDE, ESP-IDF or MicroPython, but they only provide sample code for Arduino based on EPDiy E-Paper Driver project. Typical applications listed by LilyGO include desktop weather station, STEM education, and IoT device.

TTGO T5 4.7-inch e-Paper ESP32 display is now sold for $25.51 plus shipping, but if you’d like smaller or cheaper displays the company offers variants from 1.54-inch to 3.7-inch for around $14 and up.
