Uses Eagle 5.1 + Mini48SE - This version is very similar to Maple Mini, but it does not + preserve its pinout. It also heavily utilizes second side to + achieve maximal possible density. As a consequence this version + is probably smallest STM32F103Cxx board - it has 0.5" pitch + and size is only 50.5x15mm. At the same time board uses no + extremely small components - all resistors and capacitors + are 0603 (one even 0805), LED - 1206, LDO - 1117. + Uses Eagle 6.3.0 + The design is not yet tested. + + Mini64SE - Different approach to boards based on MCU in LQFP64 package. + It has DIP48 format with 0.8" pitch. The design follows same + approach as Mini48SE and utilizes both sides. Separate + versions of design for F1 and F2/F4 series are provided. + Version for F2/F4 uses different ESD protection and lacks + external disconnect cirquitry. These changes are necessary + to enable F2/F4 chips work properly in all supported USB modes + (Device/OTG) and with different powering (self powering and + bus powering). + Uses Eagle 6.3.0 + Designs are not yet tested. + PiXe-2: 'Stamp' format, 64pin STM32F103 MCU. Eagle 5.1 Features: - Dual-in-line 0.1" grid - 0805 or larger parts -> easier assembly - Internal Maple pins available & re-configurable - modest 10mil track/space rules DIY-able -
