Ultra-Compact ESP32-C3 OLED PCB Design

Design an ultra-compact PCB in EasyEDA Standard for an ESP32-C3 & 0.42" OLED display module. Strict Requirements: 1. Form Factor: Board width must strictly be <= 8.5 mm (to fit inside a 9.5 mm inner diameter cylindrical pen casing). Board length: 40 mm - 45 mm. Thickness: 0.8 mm - 1.0 mm. 2. Microcontroller: ESP32-C3FH4 (QFN-32 bare IC with internal 4MB flash) with ceramic chip antenna clearance. 3. Display: 0.42-inch bare OLED (SSD1306/SSD1315 I2C, 16-pin ribbon footprint). 4. Power & Programming: Compact pogo pads / micro pads for 3.3V power, battery connections, and UART flashing. 5. Deliverables: EasyEDA source files, Gerber, JLCPCB-compatible BOM, and Pick & Place (CPL) files. Apply only if you have routed dense micro-strip PCBs in EasyEDA.
