Vývojové nástroje
Starter kity pre PIC32 sú nasledovné:

• PIC32 Starter Kit (DM320001) (od 49.99 USD; za DM320002 - PIC32 I/O Expansion Board 72,- USD)
  
• PIC32 USB Starter Kit II (DM320003-2)
  
• PIC32 Ethernet Starter Kit (DM320004) (od 72,- USD)

Ako development kit sa dá použiť Explorer 16 Development Board, spolu s príslušným PIM modulom.
Ako prekladač Microchip odporúča MPLAB C32 C Compiler.

Cena, dostupnosť
Napríklad PIC32MX795F512L je ocenený na 6.55 USD (@10k ks), PIC32MX575F256H na 4.73 USD (@10k ks).
Všetky modely sú už dostupné, záleží iba na distribútoroch, či ich nakúpia aj pre predaj v kusových množstvách (to ešte preverím ).
Jednotlivé ceny nájdete na tejto adrese.
