4 Hardware

The hardware of the MSP-BSL is open source. The design files are available on the Olimex website.

The MSP-BSL programmer is based on MSP430F5510. All I/Os that are not used by the standard BSL target connector (see Section 4.2) are made available as pads on the bottom of the PCB. Furthermore, there are two status LEDs (green and yellow) and two push buttons, a reset button and a button to invoke the USB BSL of the MSP430F5510.

The MSP-BSL features also an onboard 3.3-V voltage regulator that can supply up to 150 mA to the target (see Section 4.3).
