Overview
The LILYGO T-Journal is a minimalist ESP32-PICO-D4 camera development board pairing an OV2640 2-megapixel image sensor with a tiny 0.91-inch SSD1306 OLED display. Available in fisheye or normal lens variants, it runs on the dual-core 240MHz Xtensa LX6 processor with 520KB SRAM and up to 4×16MB QSPI flash. Power comes from a USB 5V/1A input or a 3.7V LiPo battery via a JST 2-pin 1.25mm connector. The board draws approximately 160mA during operation and supports WiFi 802.11 b/g/n plus Bluetooth for wireless image streaming. A dedicated Wi-Fi antenna is included. The servo control output and red power LED round out the feature set. Programming is done via a USB cable and includes GPIO32 button and reset key.
