The R14 & R15 annotation on the schematics is a very light gray color, at least that's how it looks on my laptop. A step upgrade of ESP32-WROOM-32x modules with an additional 8MB SPI PSRAM (Pseudo static RAM). Such modules can be also used for evaluation after adding a few extra components like a programming interface, bootstrapping resistors and break out headers. By default the module has 4MB flash and may be also ordered with custom flash size of 8 or 16MB, see Espressif Products Ordering Information. Which of these parts would be an appropriate replacement? The "E" (pcb antenna) version is jumpered to the pcb antenna. stream Depending on version the module has PCB antenna (shown below) or an U.FL / IPEX antenna connector. Development boards, depending on intended functionality, have exposed GPIO pins headers, provide USB programming interface, JTAG interface as well as peripherals like touch pads, LCD screen, SD card slot, camera module header, etc. 1 0 obj This section describes the latest versions of boards.
