Re: ESP32 WROOM-32 with PSRAM Module
Hello
I have removed metal chip case. I used multimeter to find which exact flash pins are connected to chip pins, I have found following
(flash PIN -> esp32 pin)
CE -> not connected to pin
SIO1 -> d0
SIO2 -> d3
VSS -> gnd
VCC -> 3.3V but no direct connection to pin
SIO3 -> d2
SCLK -> clk
SIO0 ...

ESP32 WROOM-32 with PSRAM Module
Hello,
I want to attach PSRAM memory LY68L6400SLIT with Espressif ESP32-WROOM-32 2.4GHz WiFi+Bluetooth chip. Iam using wroom adapter, I am using barebone chip. I assume that this is possible, as I have found tutorial online http://blog.pagefault-limited.co.uk/lolin32-lite-esp32-8mb-psram-upgrade ...
