Seo U se Hlokang
Ho nts'etsapele lits'ebetso tsa mojule oa ESP8685-WROOM-04 o hloka:

• 1 x ESP8685-WROOM-04 module
• 1 x Boto ea tlhahlobo ea Espressif RF
• 1 x USB-to-Serial board
• 1 x Thapo ea Micro-USB
• 1 x PC e sebelisang Linux
  Tataisong ena ea basebelisi, re nka sistimi ea ts'ebetso ea Linux joalo ka example. Bakeng sa tlhaiso-leseling e batsi mabapi le tlhophiso ea Windows le macOS, ka kopo sheba Tataiso ea Lenaneo la ESP-IDF.

Khokahano ea Hardware

1. Solder ESP8685-WROOM-04 module ho boto ea tlhahlobo ea RF joalo ka ha ho bonts'itsoe ho Setšoantšo sa 2.
2.  Hokela boto ea tlhahlobo ea RF ho boto ea USB-to-Serial ka TXD, RXD, le GND.
3.  Hokela boto ea USB-to-Serial ho PC.
4. Hokela boto ea tlhahlobo ea RF ho PC kapa adaptara ea matla ho nolofalletsa phepelo ea matla a 5 V, ka thapo ea Micro-USB.
5. Nakong ea ho jarolla, hokela IO0 ho GND ka jumper. Ebe, bula "ON" boto ea tlhahlobo.
6. Khoasolla firmware ho Flash. Ho fumana lintlha, sheba likarolo tse ka tlase.
7. Kamora ho jarolla, tlosa jumper ho IO9 le GND.
8. Matlafatsa boto ea tlhahlobo ea RF hape. ESP8685-WROOM-04 e tla fetohela ho mokhoa oa ho sebetsa. Chip e tla bala mananeo ho tloha ho flash ha e qala.

Hlokomela:
