HIZMOS Journey

the original goal was simple is to create a hardware hacking and rf device inspired by devices Flipper Zero but at a much lower price and with more powerful hardware and having every single feature i have dreamed for

why I started hizmos

I wanted to create a device that students, makers, and hardware guys could afford many existing devices are expensive or difficult to get in my region, so I started designing a platform that could combine wireless experimentation , hardware development, electronics tools, and educational features into a single device. hizmos started as a very simple project but now it is a very unique and cool device mixing the powerful software, hardware affordabilty and opensource

hizmos firmware (Beta 1.3)

Flashing ESP32-S3 Firmware with ESP Web Tool

Use the following files and flash addresses:

Address	File
0x0000	HIZMOS_OLED_U8G2lib.ino.bootloader.bin
0x8000	HIZMOS_OLED_U8G2lib.ino.partitions.bin
0x10000	HIZMOS_OLED_U8G2lib.ino.bin

Steps

1. open https://esptool.spacehuhn.com/ or any other web flasher tool
2. Click Connect and select your ESP32-S3 serial port
3. Click Add File and add:
   • HIZMOS_OLED_U8G2lib.ino.bootloader.bin at address 0x0000
   • HIZMOS_OLED_U8G2lib.ino.partitions.bin at address 0x8000
   • HIZMOS_OLED_U8G2lib.ino.bin at address 0x10000
4. Enable Erase Before Flashing
5. click Program
6. after flashing reboot the board
