Pin headers/pin sockets

• "Standard" length is 1x40 or 2x40 pins
  • Cheaper to buy 1x40 or 2x40 and cut off extra pins
• Ebay - 1x40 Header pins/sockets
• Female connectors are expensive on Mouser, Ebay has good choices
• Mouser 1x40 pin straight headers
• Mouser 1x40 right angle pin headers
• Mouser 2x40 right angle pin headers
