slimjim2

slimjim2 is a multi-purpose adapter board for RF form-factor Synapse Wireless SNAP modules like the RF100 and RF200. The original slimjim supported a custom module dubbed the TC200, but the slimjim2 drops support for it in favor of a ton of cool features. All pins are broken out to a set of standard 0.1" (2.54 mm) headers for jumper cables, breadboarding, or soldering.

Features

slimjim2 contains a few features that make using RF-style SNAP devices in one-off or development projects easier:

• 0.1" (2.54 mm) pin header breakout for all pins
• Silkscreen marks for pins
• Optionally-populated functionality:
  • 3.3V regulator capable of handling input voltages of up tp 15V
  • CH430 USB<->UART adapter for SNAP bridge applications
  • Auto-reset on DTR (for SNAP bridge applications)
  • Reset pushbutton
  • 6-pin serial header
  • Backfeed protection diode for USB power
• USB Type-C port can be used for serial data and power (if regulator and USB<->UART populated)
• 3mm mounting hole
• Module orientation marker
• Open-source hardware designs
